Description

Hair repair agent, hair treatment agent and hair treatment method

The present invention relates to a hair repair agent, a hair treatment agent and a hair treatment method, and more particularly to a hair repair agent, a hair treatment agent and a hair treatment method having an excellent hair repair effect.

In recent years, it has been common practice to perform hair treatment using treatment agents such as hair coloring agents, bleaching agents, permanent wave agents, hair straighteners (hereinafter, also referred to as straight perm agents), and treatment agents.

However, among these treatment agents, various components such as alkaline agents, oxidizing agents, reducing agents, etc. are blended, and some hair treated with hair is not a little chemically damaged. When hair is chemically damaged, it loses its luster, elasticity, moistness, silkiness, and softness, making daily care difficult, and depending on the degree of damage, it can be said to be visually beautiful hair. It will be in a non-existent state.

In addition, even if the hair is damaged and the hair is treated to obtain the desired effect, the desired effect is not always obtained. The degree of effect in hair treatment varies depending on the hair quality and hair condition of the person to be treated, and the duration of the effect also varies.

The person who performs the treatment may fine-tune the hair treatment method for each person to be treated in order to reduce the difference in the effect and the sustainability due to individual differences, but the hair damage is suppressed and repaired. It was difficult to achieve both the effect of hair treatment and the effect of hair treatment by the above treatment agent.

Patent Document 1 proposes a hair treatment agent containing a hydrolyzed protein and an anionic compound.
It is described that the pH of this hair treatment agent is preferably acidic because it is not preferable to make the pH alkaline because the hair swells.
However, there is room for further improvement in this hair treatment agent in terms of enhancing the effect of the treatment agent such as perm while suppressing and repairing damage to the hair.

The present inventor can enhance the effect of a treatment agent selected from a hair coloring agent, a bleaching agent, a permanent wave agent, a hair straightener or a treatment agent while suppressing and repairing hair damage. Was previously proposed in Patent Document 2.

It can contain trimonium chloride, methylisothiazolin, methylchloroisothiazolinone, fragrances and the like.

Further, the pH of the hair repair agent [III] can be neutral to alkaline, preferably about pH 7 to 10.

4. Hair Repair Method In the hair repair method using the first hair repair agent, the above-mentioned hair repair agent [I], the above-mentioned hair repair agent [II], and the above-mentioned hair repair agent [III] are mixed and neutral. To obtain a weakly alkaline three-component mixed hair repair agent and apply it to the hair.

When the three-component mixed hair repair agent according to the present invention as described above is adopted, the hair repair agent [I] is applied to the hair, and then the hair repair agent [II] is applied to the hair, as compared with the conventional method of applying the hair repair agent. It saves time, and has an excellent effect on repairing hair that is firm, glossy, textured, has less curly hair, has less volume, and has less dust on the tips.

The reason why such an effect is exhibited is not clear, but the effect that cannot be exhibited by simply mixing the hair repair agent [I] and the hair repair agent [II] can be obtained by combining the hair repair agent [III]. It is presumed that it is exhibited by mixing.
That is, at least one amino acid contained in the hair repair agent [III] acts on the hair repair agent [I] and the hair repair agent [II], and acts as if it were a technique called rinse-in shampoo. It is thought that it is.
The technique of rinse-in shampoo is simply rinse and shampoo because rinse is a cationic surfactant (cationic surfactant) and shampoo is an anionic surfactant (anionic surfactant). Even if they are mixed, their functions cancel each other out. By using a cationic polymer with a large molecular weight as a rinse component, the shampoo component first acts on the hair and scalp, and then the rinse component is applied to the hair. It is a technology that makes it work and makes use of the time difference to exert any effect.

In the present invention, the hair repairing agent [I] and the hair repairing agent [II] are not satisfactorily exhibited by simply mixing the hair repairing agent [I] and the hair repairing agent [II]. By using the hair repair agent [III], which contains at least one amino acid, the effect of canceling each other out by simply mixing [I] and the hair repair agent [II] is utilized by using a time difference like a rinse-in shampoo. It is inferred that the effect is exhibited.
Alternatively, before the at least one amino acid cancels each other out by mixing the hair repair agent [I] and the hair repair agent [II], the repair components of the hair repair agent [I] and the hair repair agent [II] are immediately added to the hair. It is presumed that the effect is exhibited by infiltrating the inside.

Furthermore, it is presumed that the penetration rate of the repair component into the hair is faster than that of the acidic repair agent because the three-component mixed hair repair agent is neutral to weakly alkaline. This is because the alkalinity has the effect of peeling off the cuticle of the hair (the effect of damaging the hair), so by applying an alkaline repair agent that is thought to damage the hair, the repair component penetrates into the hair. It is presumed that the repairing ingredients can be penetrated into the hair at an early stage by widening the entrance to the hair. Such an effect is more exerted when it is weakly alkaline than when it is neutral.

In this way, by repairing the hair in combination with the hair repair agent [I], the hair repair agent [II], and the hair repair agent [III], early neutralization of the hair can be achieved. ..
Some hair that has been treated with hair is chemically damaged, but this is damaged by the exposure of the hair to alkaline components. For example, treatment agents such as hair coloring agents, bleaching agents, permanent wave agents, and straightening agents are alkaline because they swell the hair and allow the treating agent to penetrate into the hair.
In this field, it has been thought that alkaline substances usually swell the hair and release the nutrients in the hair to the outside of the hair.
Therefore, hairdressers and barbers apply repair agents so as to neutralize the hair after hair treatment as soon as possible.
However, even if a repair agent is applied, it is difficult to completely neutralize it, and it often remains alkaline for many days. The longer the alkaline state lasts, the more hair damage such as dryness and hair breakage is caused.
The three-component mixed hair repair agent according to the present invention can achieve early neutralization of hair.
The time for neutralization can be achieved within 20 to 50 minutes, depending on individual differences.
This effect becomes even more remarkable in hair treatment with a four-component mixed hair treatment agent obtained by mixing the treatment agent [X] described later.

Further referring to hair damage, hair damage often involves damage to the inside of the hair, which is also called chemical or qualitative damage.
It is said that such damage is caused by the matrix (filling substance) inside the hair being damaged by a chemical such as a perm agent or a coloring agent.
Most of the internal damage is mainly caused by the outflow and deterioration of the matrix, and when the matrix is lost, the fibers tend to fall apart and become split ends, and at the same time, it also causes the dryness due to the outflow of the moisturizing component of the hair. Become.
Perms and colors mainly act on the matrix part to exert their effects, but damaged hair has the disadvantages of being less likely to be permed, less likely to be dyed, and faster to discolor. Occurs.
In the repair of the matrix, it is impossible to repair with silicon or oils and fats, and it is a very effective means to infiltrate the component that repairs the matrix into the hair.
INDUSTRIAL APPLICABILITY The present invention is very useful in that it is possible to infiltrate the nutritional component into the hair at an early stage and recover the damage of the hair at an early stage.

<Second hair repair agent (four-component mixed hair treatment agent) and hair treatment method using it>
The second hair repair agent of the present invention is a three-component mixed hair repair agent obtained by mixing a hair repair agent [I], a hair repair agent [II], and a hair repair agent [III], which is neutral to weak. It is an alkaline, four-component mixed hair treatment agent obtained by mixing the treatment agent [X] with the three-component mixed hair repair agent.

The mixing method is not particularly limited, and the hair repair agent [I], the hair repair agent [II], the hair repair agent [III], and the treatment agent [X] are added to the hair repair container at the same time, or the hair repair agent [ I], the hair repair agent [II], and the hair repair agent [III] are mixed, added to the treatment agent [X], and stirred and mixed with a stirrer or a stirring rod.

1. 1. Hair repair agent [I]
The hair repair agent [I] constituting the second hair repair agent of the present invention contains at least a hydrolyzed protein and an amino acid derivative, and is a hair repair agent constituting the first hair repair agent of the present invention described above. Since it is the same as the agent [I], those explanations will be used, and the description here will be omitted.

2. 2. Hair repair agent [II]
The hair repair agent [II] constituting the second hair repair agent of the present invention contains at least a small molecule keratin, a medium molecule keratin and an amino acid derivative, and is the above-mentioned first hair repair agent of the present invention. Since it is the same as the constituent hair repair agent [II], those explanations will be used, and the description here will be omitted.

3. 3. Hair repair agent [III]
The hair repair agent [III] constituting the second hair repair agent of the present invention contains at least 10 kinds of amino acids, and the hair repair agent constituting the first hair repair agent of the present invention described above [ Since it is the same as III], those explanations will be used, and the explanations here will be omitted.

4. Treatment agent [X]
The treatment agent [X] constituting the second hair repair agent of the present invention is selected from a hair coloring agent, a bleaching agent, a permanent wave agent, a hair straightener or a treatment agent.

The treatment agent [X] is not particularly limited as long as it is a treatment agent capable of desired hair treatment, and may be a commercially available product. The treatment agent on the market is a product that is supposed to be treated by the user himself, and contains a large amount of oil to prevent the scalp and hair from drying, so that the treatment agent does not contain a large amount of oil. It is preferably a treatment agent.
When a commercially available product is used as the treatment agent [X], a generally commercially available hair coloring agent, bleaching agent, permanent wave agent, and hair straightener can be used as they are because they are alkaline.
When a commercially available product is used as the treatment agent, it is preferable to add an alkaline agent to make it alkaline because the commercially available treatment agent is usually acidic.
The alkaline agent is not particularly limited, but arginine or the like can be preferably used.
When a permanent wave agent is used as the treatment agent [X], it may be diluted when mixed with the hair repair agent [I], the hair repair agent [II], and the hair repair agent [III]. preferable. This can slow down the rate of neutralization and apply the desired permanent.

5. Hair Treatment Method The hair repair method (hair treatment method) using the second hair repair agent includes the above-mentioned hair repair agent [I], the above-mentioned hair repair agent [II], and the above-mentioned hair repair agent [III]. The three-component mixed hair repair agent obtained by mixing with is neutral to weakly alkaline, and the treatment agent [X] is mixed with the three-component mixed hair repair agent to obtain a four-component mixed hair treatment agent, and the hair is obtained. Apply to.

When the four-component mixed hair treatment agent according to the present invention as described above is adopted, the hair repair agent [I] is applied to the hair, then the treatment agent [X] is applied to the hair, and then the hair repair agent [II] is applied. Compared to the conventional method of applying to hair, it saves time for application and processing, and also has an excellent effect of repairing hair with elasticity, luster, texture, curly hair, volume, and dust on the tips. ..
In addition, since the hair itself is repaired by the hair repair effect, the effect of hair treatment by the treatment agent is also improved.
Further, as described above, the effect of early neutralizing the alkaline hair can be achieved.

The treatment agent [X] is alkaline. In this field, it has been thought that alkaline substances usually swell the hair and release the nutrients in the hair to the outside of the hair.
Therefore, it was common sense to neutralize the hair with an acid rinse or the like after treating the hair with the alkaline treatment agent [X].

According to the present embodiment, after applying the four-component mixed hair treatment agent, the pH of the hair on the alkaline side is maintained at neutral without using a substance having a pH adjusting action, so that the hair is neutralized by an acid rinse. The effect of the treatment agent [X] can be enhanced while suppressing and repairing damage to the hair.
In addition, the effect of repairing hair with firmness, luster, texture, curly hair, volume, and dust on the tips of the hair is good.

The reason why the effect of this embodiment is exhibited is presumed as follows.
An acidic hair treatment agent [I] containing a hydrolyzed protein such as keratin and an amino acid derivative having the structure of glutamic acid such as sodium dilauroyl glutamate, low molecular weight keratin and medium molecular weight keratin, for example lysine dilauroyl glutamate. An alkaline hair repair agent [II] containing an amino acid derivative having a glutamic acid structure such as sodium, and a neutral to alkaline hair repair agent [III] containing at least one amino acid, for example, alkaline. When a hair dye (hair coloring agent) is mixed as a certain treatment agent [X], the mixed solution is alkaline.
When the mixed solution is applied to the hair, the cuticle of the hair is opened by the alkaline component, hydrogen peroxide (H ₂ O ₂ ) and the dye permeate the inside of the hair, and the hydrogen peroxide decomposes the melanin pigment. The hair is bleached, and at the same time, the dye, which is initially colorless, combines with hydrogen peroxide to develop color and dye the hair.
The molecules that make up the oxidized dye grow by sticking to each other, making it difficult for them to get out of the hair through the gaps in the cuticle.
However, in this state, it is assumed that the pH of the hair is alkaline due to the alkaline mixture. If the pH of the hair is alkaline, the cuticle will remain open and the hair may be damaged.
However, according to the mixed solution in the present embodiment, the hair repairing agent [I] and the hair repairing agent [II] are mixed together to produce an effect that is not satisfactorily exhibited by simply mixing the hair repairing agent [I] and the hair repairing agent [II]. Therefore, the effect of canceling each other by simply mixing the hair repair agent [I] and the hair repair agent [II] can be counteracted by the hair repair agent [III] containing at least one amino acid. The effect is exhibited by utilizing such a time difference, and as a result, the repairing action of each of the hair repairing agent [I] and the hair repairing agent [II] is performed in a state where the hair surface is open due to the alkaline pH of the hair. However, it is presumed that the effect of promoting early penetration into the hair without canceling each other and early expressing the self-repairing ability of the hair itself is achieved.
Early neutralization (pH) can be achieved by the early expression of the self-repairing ability of the hair itself. The time for neutralization can be achieved within 20 to 50 minutes, depending on individual differences.
In addition, when a hair dye (hair coloring agent) is used as the treatment agent [X], it is presumed from the state of the hair after that that hydrogen peroxide, which may have an adverse effect on the hair, is sufficiently removed. To.

Although the preferred embodiment of the present invention has been described above, in the hair repair method using the three-component mixed hair repair agent, the above-mentioned three-component mixed hair repair agent is applied to the hair, and then the treatment agent [X] is applied to the hair. Is also a preferred embodiment.
Further, it is also a preferable embodiment to apply the three-component mixed hair repair agent a plurality of times after treating the hair with the treatment agent [X]. The repair effect is further increased by repeating the application.

Further, in the hair treatment method using the 4-component mixed hair treatment agent, after applying the above-mentioned 3-component mixed hair repair agent to the hair, the 4-component mixed hair treatment agent containing the treatment agent [X] is applied to the hair. Is also a preferred embodiment.
Also in this case, it is a preferable embodiment to apply the three-component mixed hair repair agent a plurality of times after treating the hair with the four-component mixed hair treatment agent containing the treatment agent [X].

Further, the hair repair method of the present invention is not limited to this. For example, a separate pretreatment agent may be used before the treatment of the present invention, or a separate post-treatment agent may be used after the treatment of the present invention. At this time, as the pretreatment agent or the post-treatment agent, any one of the hair repair agent [I], the hair repair agent [II], and the hair repair agent [III] may be used, and one or two of them may be used. You may select more than seeds and use them in combination.

In the present invention, the method for applying the three-component mixed hair repair agent or the four-component mixed hair treatment agent is not particularly limited, and can be applied in the form of foam, liquid, milk, gel, cream, or the like. In particular, it is preferable to apply it in the form of foam from the viewpoint that it can be applied evenly and evenly and efficiently applied to the entire hair with a small amount of application.

The three-component mixed hair repair agent or the four-component mixed hair treatment agent may be applied as it is (as it is) or diluted with water or the like. It is preferable for the undiluted solution to have a repair effect.

<Other hair repair methods (1)>
In the other hair repair method (1) of the present invention, a treatment agent [X] selected from a hair coloring agent, a bleaching agent, a permanent wave agent, a hair straightener or a treatment agent is applied to the hair.
After a predetermined time has passed after the application of the treatment agent [X],
Hair repair agent [I] containing at least hydrolyzed protein and amino acid derivative,
A hair repair agent [II] containing at least low-molecular-weight keratin, medium-molecular-weight keratin, and amino acid derivatives, and
A neutral to weakly alkaline three-component mixed hair repair agent, which is a mixture of a hair repair agent [III] containing at least one amino acid, is applied to the hair.

The hair repair agent [I] contains at least a hydrolyzed protein and an amino acid derivative, and is the same as the hair repair agent [I] constituting the first hair repair agent of the present invention described above. The explanation will be used, and the explanation here will be omitted.

Further, the hair repair agent [II] contains at least a small molecule keratin, a medium molecule keratin, and an amino acid derivative, and is the same as the hair repair agent [II] constituting the first hair repair agent of the present invention described above. Therefore, those explanations will be used, and the explanations here will be omitted.

Further, the hair repair agent [III] contains at least one amino acid and is the same as the hair repair agent [III] constituting the first hair repair agent of the present invention described above. The explanation will be used, and the explanation here will be omitted.

Furthermore, the treatment agent [X] is selected from a hair coloring agent, a bleaching agent, a permanent wave agent, a hair straightener or a treatment agent, and constitutes the second hair repair agent of the present invention described above. Since it is the same as the treatment agent [X], those explanations will be incorporated, and the description here will be omitted.

Another hair repair method (1) of the present invention is characterized in that the treatment agent [X] is applied to the hair, and a predetermined time elapses after the application.
Here, the predetermined time is the time for completing the hair treatment with the treatment agent [X].
The hair treatment agent is often used after being adjusted to be alkaline to swell the hair in order to allow the treatment component to penetrate into the inside of the hair.
Therefore, the conventional wisdom of hair treatment is that hairdressers and barbers who perform hair treatment finish hair treatment in a short time in order to avoid damage to the hair as much as possible.

In this case, since the hair treatment is completed in a short time, the treatment component does not penetrate firmly into the hair, and the desired hair treatment is not always achieved. However, the fact is that hairdressers and barbers accept the situation where the treatment effect is reduced and finish the hair treatment in a short time, rather than making the hair itself seriously damaged and difficult to repair. be. It is a very serious problem that the hair itself is seriously damaged and difficult to repair.

The other hair repair method of the present invention is characterized in that the hair treatment time with the treatment agent [X] is longer than usual.

In the case of a hair coloring agent, it is generally washed off in about 20 to 40 minutes, but in the other hair repair method of the present invention, the three-component mixed hair repair agent is applied to the hair after about 25 to 50 minutes have passed.
In the case of a bleaching agent, the hair is generally washed away in about 10 to 30 minutes, but in the other hair repair method of the present invention, the three-component mixed hair repair agent is applied to the hair after about 15 to 40 minutes have passed.
In the case of a permanent wave agent, it is generally washed off in about 5 to 30 minutes, but in the other hair repair method of the present invention, the three-component mixed hair repair agent is applied to the hair after about 10 to 40 minutes have passed.
In the case of a hair straightener, it is generally washed off in about 5 to 30 minutes, but in the other hair repair method of the present invention, the three-component mixed hair repair agent is applied to the hair after about 10 to 40 minutes have passed.

The other hair repair method of the present invention completes the desired hair treatment by firmly infiltrating the treatment component into the hair by prolonging the treatment time by about 1.2 to 2 times as compared with the general treatment time. It is possible to achieve a high hair repair effect while making it.

<Other hair repair methods (2)>
Further, other hair repair methods of the present invention can be used.
Hair repair agent [I] containing at least hydrolyzed protein and amino acid derivative,
A hair repair agent [II] containing at least low-molecular-weight keratin, medium-molecular-weight keratin, and amino acid derivatives, and
A neutral to weakly alkaline three-component mixed hair repair agent mixed with a hair repair agent [III] containing at least one amino acid, and
A four-component mixed hair treatment agent in which a treatment agent [X] selected from a hair coloring agent, a bleaching agent, a permanent wave agent, a hair straightener or a treatment agent is mixed with the three-component mixed hair repair agent is applied to the hair. death,
After applying the 4-liquid mixed hair treatment agent mixed with the treatment agent [X] and after a predetermined time has elapsed,
Hair repair agent [I] containing at least hydrolyzed protein and amino acid derivative,
A hair repair agent [II] containing at least low-molecular-weight keratin, medium-molecular-weight keratin, and amino acid derivatives, and
A neutral to weakly alkaline three-component mixed hair repair agent, which is a mixture of a hair repair agent [III] containing at least 10 kinds of amino acids, is applied to the hair.

In the other hair repair method (1) of the present invention, the other hair repair method (2) of the present invention replaces the treatment agent [X] with a hair repair agent [I], a hair repair agent [II], and a hair repair. This is an embodiment in which a four-component mixed hair treatment agent in which the agent [III] and the treatment agent [X] are mixed is used.
Also in this embodiment, a four-component mixed hair treatment agent is applied to the hair, and a predetermined time elapses after the application.

The hair repair agent [I], the hair repair agent [II], the hair repair agent [III], and the treatment agent [X] used are the same as the other hair repair method (1) of the present invention. Use it.

Also in the other hair repair method (2) of the present invention, the treatment component is firmly permeated into the hair and desired by prolonging the treatment time by about 1.2 to 2 times as compared with the general treatment time. It is possible to achieve a high hair repair effect while completing the hair treatment.

It should be noted that the four-component mixed hair treatment agent is applied to the hair, and after a predetermined time has passed after the application, the four-component mixed hair treatment is performed before the three-component mixed hair repair agent, which is the first hair repair agent, is applied to the hair. The agent may be washed away, but from the viewpoint of keeping the hair repairing component on the hair at all times, it is preferable to apply the first hair repairing agent, a three-component mixed hair repairing agent, to the hair without washing it off.

Hereinafter, examples of the present invention will be described, but the present invention is not limited to such examples.

From Table 2, it was found that the three-component mixed hair repair agent 5 to 8 exerts the effects of repairing hair, such as firmness, luster, texture, curly hair, and volume, and the dust on the tips of the hair. rice field.
Further, from the results in Table 2, it can be seen that the repair effect is lowered when the proportion of the hair repair agent [I] and the hair repair agent [II] is lower than that of the hair repair agent [III].

(Example 3)
1.4 Preparation of liquid-mixed hair treatment agent A four-component mixed hair treatment agent was prepared as follows.

(4 liquid mixed hair treatment agent 1)
Using a hair coloring agent (pH 10th place) as the treatment agent [X], the hair coloring agent [I] is 3 g in the undiluted solution and the hair repair agent [II] is 3 g in the undiluted solution in 80 g of the hair coloring agent. A neutral to weakly alkaline three-component mixed hair repair agent mixed with 20 g of the agent [III] was mixed to prepare a four-component mixed hair treatment agent 1.
As the hair repair agent [I], the hair repair agent [II], and the hair repair agent [III], those having the same composition as the three-component mixed hair repair agent of Example 1 were used.

(4 liquid mixed hair treatment agent 2)

3. 3. Evaluation The hair repair effect was evaluated based on the same evaluation criteria with respect to the same evaluation items as in Example 1.
In addition, it was measured how long it took for the hair to be neutralized after the four-component mixed hair treatment agent was applied to the hair.
The above results are shown in Table 3.

From Table 3, the effects of hair repair, such as firmness, luster, texture, curly hair, and volume, and the dusting of hair tips, are exhibited by the four-component mixed hair repair agents 1, 2, and 3. I found out.
Further, it was found that the hair was neutralized in about 30 to 45 minutes even though the hair coloring agent had a pH of about 10.
Moreover, when the hair after the treatment was followed up, it was confirmed that the hair dyeing did not proceed. It is presumed that this is because the hydrogen peroxide contained in the coloring agent has been sufficiently removed and does not remain inside the hair.

(Example 4)
1.4 Preparation of liquid-mixed hair treatment agent A four-component mixed hair treatment agent was prepared as follows.

(4 liquid mixed hair treatment agent 4)
Using a straight perm agent (pH 12 position) as the treatment agent [X], 3 g of the hair repair agent [I] in the undiluted solution and 3 g of the hair repair agent [II] in the undiluted solution in 100 g of the straight perm agent, hair repair A neutral to weakly alkaline three-component mixed hair repair agent mixed with 5 g of the agent [III] was mixed to prepare a four-component mixed hair treatment agent 4.

The treatment agent 6 was prepared.

(4 liquid mixed hair treatment agent 7)
In the four-component mixed hair treatment agent 4, 2 g of the hair repair agent [I] was diluted (4-fold diluted) with 8 g of water, and the hair repair agent [II] was replaced with 2 g of the undiluted solution and 20 g of the hair repair agent [III]. A four-component mixed hair treatment agent 7 was prepared in the same manner except that the changes were made.

2. 2. Hair Treatment Model D hair treatment was performed using the obtained 4-liquid mixed hair treatment agents 4, 5, 6 and 7. The hair treatment was performed with the same hair in different places.

3. 3. Evaluation The hair repair effect was evaluated based on the same evaluation criteria with respect to the same evaluation items as in Example 1.
In addition, it was measured how long it took for the hair to be neutralized after the four-component mixed hair treatment agent was applied to the hair.
The above results are shown in Table 4.

From Table 4, the effects of hair repair, such as firmness, luster, texture, curly hair, and volume, and the dusting of hair tips, are demonstrated by the four-component mixed hair repair agents 4, 5, 6, and 7. It turned out that.

Further, it was found that the hair of the four-component mixed hair repair agents 4, 5 and 6 was neutralized in about 20 to 45 minutes even though the straight perm agent had a pH of about 12. Furthermore, it was found that the time for neutralization was shortened by using the undiluted hair repair agent [I] as compared with the four-component mixed hair repair agent 7.

(Example 5)
1. 1. Hair treatment method longer than normal treatment time A bleaching agent (pH 12 position) was used as the treatment agent [X], and the hair repair agent 2 in Example 1 was used as the hair repair agent.
The bleaching agent was applied to the hair of Model E and left for about 30 minutes. After that, the bleaching agent was washed away, and the hair repair agent 2 in Example 1 was applied to the hair.

2. 2. Hair Treatment Method Using Normal Treatment Time A bleaching agent (pH 12 position) was used as the treatment agent [X], and the hair repair agent 2 in Example 1 was used as the hair repair agent.
The bleaching agent was applied to the hair of Model E and left for about 20 minutes. After that, the bleaching agent was washed away, and the hair repair agent 2 in Example 1 was applied to the hair.

Hair treatment was performed with the same hair in different places.

The hair repair effect was evaluated for the same evaluation items as in Example 1 based on the same evaluation criteria.
In addition, the hair treatment results were evaluated.
The above results are shown in Table 5.

From Table 5, the hair treatment method that is longer than the normal treatment time has the effect of repairing the hair as compared with the hair treatment method that uses the normal treatment time. It was found that it exerts the effect of reducing the stickiness. In addition, it can be seen that the desired decolorization is performed and the hair treatment is also excellent.
The present inventor confirmed the same result in an experiment using a straight perm agent or a perm agent.

(Example 6)
1. 1. Hair treatment method longer than normal treatment time Using a straight perm agent (pH 12 position) as the treatment agent [X], 100 g of the straight perm agent, 5 g of the hair repair agent [I] in the undiluted solution, and the hair repair agent [ A neutral to weakly alkaline three-component mixed hair repair agent, which is a mixture of 5 g of the undiluted solution of II] and 50 g of the hair repair agent [III], was mixed to prepare a four-component mixed hair treatment agent.
As the hair repair agent [I], the hair repair agent [II], and the hair repair agent [III], those having the same composition as that of the three-component mixed hair repair agent 2 of Example 1 were used.
The 4-liquid mixed hair treatment agent was applied to the hair of Model F and left for about 35 minutes. After that, the 4-liquid mixed hair treatment agent was washed away, and the hair repair agent 2 of Example 1 was applied to the hair.

2. 2. Hair treatment method with normal treatment time Using a straight perm agent (pH 12 position) as the treatment agent [X], 100 g of the straight perm agent, 5 g of the hair repair agent [I] in the undiluted solution, and the hair repair agent [II]. A neutral to weakly alkaline three-component mixed hair repair agent, which is a mixture of 5 g of the undiluted solution and 50 g of the hair repair agent [III], was mixed to prepare a four-component mixed hair treatment agent.
As the hair repair agent [I], the hair repair agent [II], and the hair repair agent [III], those having the same composition as that of the three-component mixed hair repair agent 2 of Example 1 were used.
The four-component mixed hair treatment agent was applied to the hair of Model F and left for about 20 minutes. After that, the 4-liquid mixed hair treatment agent was washed away, and the hair repair agent 2 of Example 1 was applied to the hair.

Hair treatment was performed with the same hair in different places.

The hair repair effect was evaluated for the same evaluation items as in Example 1 based on the same evaluation criteria.
In addition, the hair treatment results were evaluated.
The above results are shown in Table 6.

From Table 6, the hair treatment method that is longer than the normal treatment time has the effect of repairing the hair as compared with the hair treatment method that uses the normal treatment time. It was found that it exerts the effect of reducing the stickiness. In addition, it can be seen that the curly hair is firmly straightened and it is also excellent as a hair treatment.
The present inventor confirmed the same result in an experiment using a straightening agent and a perming agent.

(Example 7)
The hair repair agent of Example 1 was used for Model G, in which the condition of the hair was very damaged, there was no elasticity or gloss, the dryness was noticeable visually, the texture was very poor, and there were many hair breaks. Hair treatment was performed according to 2.
The hair repair effect was evaluated for the same evaluation items as in Example 1 based on the same evaluation criteria.
As a result, it was confirmed that the effects of elasticity, luster, texture, curly hair, volume, and dust on the tips of the hair were suppressed.

Model G tried a commercially available treatment for his own hair multiple times, but it was said that there was no repair effect at all, but the hair treatment with the hair repair agent according to the present invention was performed. As a result, it was confirmed that even for hair that cannot be repaired with ordinary repair agents, the effects of elasticity, luster, texture, curly hair, volume, and dust on the tips of the hair are suppressed.

(Example 8)
1.3 Preparation of liquid mixed hair repair agent A hair repair agent was prepared as follows.

(3 liquid mixed hair repair agent 9)
A three-component mixed hair repair agent 9 was prepared by mixing 5 g of the hair repair agent [I] with the undiluted solution, 5 g of the hair repair agent [II] with the undiluted solution, and 50 g of the hair repair agent [III].
The hair repair agent [I] contained a plurality of types of keratin, a plurality of types of collagen, and sodium dilauroyl glutamate lysine at a ratio of 1: 1: 0.2 (weight ratio) to make a liquid.
The hair repair agent [II] contained keratin having a weight average molecular weight of 300, keratin having a weight average molecular weight of 3000, and sodium dilauroyl glutamate in a ratio of 1: 1: 0.2 (weight ratio) to make it liquid.
The hair repair agent [III] contained water, arginine, aspartic acid, threonine, serine, taurine, alanine, glycine, and glutamic acid to form a cream.
The pH of the three-component mixed hair repair agent 9 was weakly alkaline, about 7 to 8.

(3 liquid mixed hair repair agent 10)
Citric acid was further added to the three-component mixed hair repair agent 9 to prepare a three-component mixed hair repair agent 10.
The pH of the three-component mixed hair repair agent 10 was about 6 weakly acidic.

2. 2. Hair Treatment Using the obtained three-component mixed hair repair agents 9 and 10, the hair of Model H after shampooing was repaired. Hair repair was performed at the same time by changing the location with the same hair.

3. 3. Evaluation The hair repair effect was evaluated based on the same evaluation criteria with respect to the same evaluation items as in Example 1.
As a result, with respect to the three-component mixed hair repair agent 9, the effects of elasticity, luster, texture, curly hair, volume, and dust on the tips of the hair are suppressed to the same extent as the hair repair agent 2 of Example 1. I was able to confirm that.
On the other hand, it was confirmed that the three-component mixed hair repair agent 10 was glossy, but the entire hair was slightly expanded, and the tips of the hair were slightly expanded and caught.
It is presumed that this is due to the pH of the three-component mixed hair repair agent. That is, the weakly alkaline three-component mixed hair repair agent 9 can keep the cuticle of the hair open due to its alkaline component as compared with the weakly acidic three-component mixed hair repair agent 10, and the hair contained therein. It is presumed that this is due to the fact that the nutritional components of the hair can penetrate early.

(Example 9)
1.4 Preparation of liquid-mixed hair treatment agent A four-component mixed hair treatment agent was prepared as follows.

(4 liquid mixed hair treatment agent 8)
Using a hair coloring agent (pH 10th place) as the treatment agent [X], the hair coloring agent [I] is 2 g in the undiluted solution and the hair repair agent [II] is 2 g in the undiluted solution in 80 g of the hair coloring agent. A neutral to weakly alkaline three-component mixed hair repair agent mixed with 20 g of the agent [III] was mixed to prepare a four-component mixed hair treatment agent 8.
As the hair repair agent [I], the hair repair agent [II], and the hair repair agent [III], those having the same composition as the three-component mixed hair repair agent of Example 1 were used.
The pH of the 4-liquid mixed hair treatment agent 8 was weakly alkaline, about 7 to 8.

(4 liquid mixed hair treatment agent 9)
Citric acid was further added to the 4-component mixed hair treatment agent 8 to prepare a 4-component mixed hair treatment agent 9.
The pH of the 4-liquid mixed hair treatment agent 9 was about 6 weakly acidic.

2. 2. Hair Treatment Model I hair treatment was performed using the obtained 4-liquid mixed hair treatment agents 8 and 9. Hair treatment was performed at the same time by changing the location of the same hair.

3. 3. Evaluation The hair repair effect was evaluated based on the same evaluation criteria with respect to the same evaluation items as in Example 1.
As a result, it was confirmed that the four-component mixed hair treatment agent 8 exerts the effects of reducing the elasticity, gloss, texture, curly hair, reducing the volume, and suppressing the dusting of the hair tips. In addition, it was confirmed that the hair breakage became less noticeable. Furthermore, it was confirmed that the dyeing condition with the coloring agent was also very good.
On the other hand, the 4-component mixed hair repair agent 9 had a better texture, but was glossy but dull, the tips of the hair were slightly widened, the hair was slightly cut, and the hair was dyed with the coloring agent. I confirmed that I was feeling sick.
It is presumed that this is due to the pH of the four-component mixed hair treatment agent. That is, the weakly alkaline 4-component mixed hair treatment agent 8 can keep the cuticle of the hair open due to its alkaline component as compared with the weakly acidic 4-component mixed hair repair agent 9, and the hair contained therein. It is presumed that this is due to the fact that the nutritional components and the components of the coloring agent can penetrate early.

1.3 Preparation of liquid mixed hair repair agent A hair repair agent was prepared as follows.

(3 liquid mixed hair repair agent 11)
A three-component mixed hair repair agent 11 was prepared by mixing 5 g of the hair repair agent [I] with the undiluted solution, 5 g of the hair repair agent [II] with the undiluted solution, and 30 g of the hair repair agent [III].
The hair repair agent [I] contained a plurality of types of keratin, a plurality of types of collagen, and sodium dilauroyl glutamate lysine at a ratio of 1: 1: 0.2 (weight ratio) to make a liquid.
The hair repair agent [II] contained keratin having a weight average molecular weight of 300, keratin having a weight average molecular weight of 3000, and sodium dilauroyl glutamate in a ratio of 1: 1: 0.2 (weight ratio) to make it liquid.
The hair repair agent [III] contained water, arginine, aspartic acid, threonine, serine, taurine, alanine, glycine, and glutamic acid to form a cream.
The pH of the three-component mixed hair repair agent 11 was neutral.
In addition, the three-component mixed hair repair agent 11 was used as an out bath treatment (a treatment that does not wash away).

(Comparative hair repair agent)
An out bath treatment made by another company was used. Out bath treatments made by other companies are weakly acidic and contain a lot of normal oil.

2. 2. Hair Treatment Model J's hair was repaired using a three-component mixed hair repair agent 11 and an out bath treatment manufactured by another company. Hair repair was performed at the same time by changing the location with the same hair. Hair repair was applied to wet hair after shampooing.

3. 3. Evaluation (1) Immediately after application, (2) Morning of application day, (3) Evening of application day, (4) After shampoo on the second day, (5) One week later, follow-up of hair was performed.
The results were as follows.

"Three-component mixed hair repair agent 11"
(1) Immediately after application; no stickiness. There was a feeling that the treatment had penetrated into the hair. After that, when the hair was dried, it was confirmed that the hair was cohesive.
(2) Morning of application day; Good texture.
(3) Evening on the day of application; hair breakage is not noticeable.
(4) After shampooing on the second day; the hair felt soft. I felt that the inside of the hair was moisturized, and I was able to confirm that it was well organized.
(5) After 1 week; Good results were confirmed for the same evaluation items as in Example 1. In addition, it was confirmed that the condition of the hair improved steadily as time passed after application.

"Out bath treatment made by other companies"
(1) Immediately after application; There is a feeling that oil remains on the surface, and the hair feels heavy. It is believed that the out bath treatments made by other companies on the market are due to the fact that they contain normal oil.
(2) Morning of application day; glossy. This also seems to be due to oil.
(3) Evening on the day of application; Although it was glossy, hair breakage became noticeable.
(4) After shampooing on the second day; the difference in gloss was no longer different from that of the three-component mixed hair repair agent 11. It was confirmed that the hair breakage was conspicuous.
(5) After 1 week; no change was observed in the hair condition as compared with immediately after application.

From the above evaluation, it is possible to make the hair cohesive and glossy immediately after application by the out bath treatment made by other companies, which is a commercial product that contains normal oil, due to its oil component. However, with the passage of time, it dries and hair breaks become noticeable.
On the other hand, it was confirmed that the three-component mixed hair repair agent according to the present invention improves the condition of the hair steadily as time passes after application.

The hair repair agent [I] contained a plurality of types of keratin, a plurality of types of collagen, and sodium dilauroyl glutamate lysine at a ratio of 1: 1: 0.2 (weight ratio) to make a liquid.
The hair repair agent [II] contained keratin having a weight average molecular weight of 300, keratin having a weight average molecular weight of 3000, and sodium dilauroyl glutamate in a ratio of 1: 1: 0.2 (weight ratio) to make it liquid.
The hair repair agent [III] contained water, arginine, aspartic acid, threonine, serine, taurine, alanine, glycine, and glutamic acid to form a cream.
The pH of the three-component mixed hair repair agent 11 was slightly alkaline.

(3 liquid mixed hair repair agent 13)
The one in which the arginine of the three-component mixed hair repair agent 12 was not additionally mixed was designated as the three-component mixed hair repair agent 13.
The pH of the three-component mixed hair repair agent 13 was neutral.

2. 2. Hair Treatment Model K hair was repaired using the three-component mixed hair repair agent 12 and the three-component mixed hair repair agent 13. Hair repair was performed at the same time by changing the location with the same hair. Hair repair was applied to wet hair after shampooing.
In addition, the same hair repair was performed on the model L.

3. 3. Evaluation (model K)
It was confirmed that the three-component mixed hair repair agent 12, which was additionally mixed with arginine, immediately became familiar with the repair agent immediately after application. Moreover, on the second day, it was confirmed that there was gloss. Further, after one week, good results were confirmed for the same evaluation items as in Example 1.
Immediately after application of the three-component mixed hair repair agent 13 without additional mixing of arginine, the hair was slightly entangled in the hands, but after one week, good results could be confirmed for the same evaluation items as in Example 1. rice field.

(Model L)
It was confirmed that the three-component mixed hair repair agent 12, which was additionally mixed with arginine, had less spread of hair, had good gloss, had good habits, and had good hair breakage on the third day after application.
The three-component mixed hair repair agent 13 without additional mixing of arginine did not have a better spread of hair than the three-component mixed hair repair agent 12 on the third day after application, but the other three-component mixed hair repair agents. It was confirmed that the effect was about the same as that of 12.

From the above evaluations, it was found that the three-component mixed hair repair agents 12 and 13 are neutral to slightly alkaline, so that the repair component permeates the inside of the hair and the hair quality can be improved at an early stage. It was also found that the more alkaline, the higher the early permeability and the early effect.
