<Hair treatment method>

FIG. 1 is an explanatory diagram of steps of a hair treatment method of the present invention.

1. Embodiment 1

FIG. 1 (A) shows a hair treatment method according to Embodiment 1, which is the first step of applying [I agent], and then applying a member selected from the group consisting of a hair dye, a bleach, a perm agent, a natural curly hair corrector, or The second step of the treatment agent X of the hair conditioner.

The treatment agent X is not particularly limited as long as it is a treatment agent capable of performing desired hair treatment, and a commercially available product can be appropriately selected.

Since the treatment agent X is alkaline. When a commercially available product is used as the treatment agent X, when a general commercially available product is used as a hair coloring agent, a bleaching agent, a perm agent, or a natural curly hair correcting agent, it can be used as it is alkaline.

When a commercially available product is used as a hair conditioner, since a commercially available hair conditioner is generally acidic, an alkaline agent can be added to make it alkaline before use.

The alkali agent is not particularly limited, and arginine and the like can be appropriately used.

The hair treatment agent [I agent] of the present invention is composed of at least keratin, collagen, and sodium bis (lauramine glutamic acid) sodium amine. [I agent] is acidic.

[I agent] Contents of keratin, collagen, and di (laurylamine glutamic acid) sodium amine, for example, when the total weight of the three ingredients is set to 100 parts by weight, the keratin is 10 to 80 weight Parts, 10 to 80 parts by weight of collagen, and 1 to 50 parts by weight of sodium bis (laurylamine glutamic acid) lysine.

The keratin contained in [I agent] is not particularly limited, but may be exemplified Examples include hydrolyzed keratin derived from wool, hydrolyzed keratin derived from feathers, hydroxypropyl hydrolyzed keratin, and hydroxypropyl trimethylammonium chloride hydrolyzed keratin.

The keratin contained in the [I agent] may be used alone or in combination of a plurality of keratins, but from the viewpoint of further improving the effect of the present invention, it is particularly preferable to use a mixture of a plurality of keratins. When mixing a plurality of kinds of keratin, it is better that the weight average molecular weight of each keratin is different, and keratins having different weight average molecular weight are more preferably mixed with more than six kinds. Thereby, the effect of suppressing hair damage and repairing can be further enhanced.

The collagen contained in the [I agent] is not particularly limited, but may be hydrolyzed collagen, isostearine hydrolyzed collagen AMPD, and the like.

The collagen contained in the [agent I] may be used alone or in combination of a plurality of collagens, but from the viewpoint of further improving the effect of the present invention, it is particularly preferable to use a mixture of a plurality of collagens. When mixing a plurality of collagens, it is preferable that the collagens have different weight-average molecular weights, and collagens with different weight-average molecular weights are more preferably mixed with two or more collagens. Thereby, the effect of suppressing hair damage and repairing can be further enhanced.

In order to obtain the best effect of suppressing hair damage and repair, the weight average molecular weight of the ingredients contained in the hair treatment agent is very important. The reason is that by providing keratin and collagen with a weight-average molecular weight corresponding to the size and degree of the damaged part of the hair, the inhibition and repair of the damage can be promoted. Therefore, in order to obtain the effect of suppressing hair damage and repair as expected by the present invention, in accordance with the repair content of the hair damage portion, keratin and collagen with different weight average molecular weights are selected, and the best combination is used. law.

The weight average molecular weights of keratin and collagen, and the general effect of these on hair are as follows.

(1) Weight average molecular weight is tens of thousands: Strengthen hair fibers, strengthen film-forming properties, and strengthen elasticity

(2) Weight average molecular weight is thousands: balance of elasticity and softness

(3) The weight-average molecular weight is hundreds: promote softness and flexibility

In particular, from the viewpoint of improving the effect of the treatment agent X, it is more preferable to contain keratin and collagen having a weight average molecular weight of several thousands.

[I agent] It contains sodium bis (lauramine glutamic acid) sodium amine. Bis (laurylamine glutamic acid) sodium lysine has high permeability to the hair and repairs the damaged part, and can improve the effect of the treatment agent X. Examples of commercially available products of sodium bis (laurylamine glutamic acid) lysinate include "Perisea L-30" manufactured by Asahi Kasei Chemicals Corporation.

[I agent] It is more preferable to contain a foaming component. By containing a foaming component, [I agent] can be applied to hair in a foam form, can be applied uniformly without omission, and can be efficiently applied to the entire hair with a small amount of application. In addition, by applying in the form of a bubble, the penetration rate of the [I agent] and the treatment agent X can be increased, and the effect of shortening the operation time can also be expected.

The foaming component is not particularly limited as long as it can make the [I agent] foamy. An anionic surfactant, a cationic surfactant, a zwitterionic surfactant, and a nonionic surfactant can be used. From the viewpoint of compatibility of the other ingredients contained in the agent, a zwitterionic surfactant is preferred.

As long as the effect of the present invention is not impaired, other components such as other ingredients, moisturizing ingredients, and plant-derived extracts may be appropriately blended in the [I agent].

Suitable moisturizing ingredients include betaine, urea, and sodium pyrrolidone carboxylate. The moisturizing component is not particularly limited, but it is preferable to include a plurality of moisturizing components from the viewpoint of achieving effective moisturizing. By achieving effective moisturization, the hair after the hair treatment of the present invention can enhance gloss, elasticity, moisturizing feeling, refreshing feeling, softness, degree of treatment agent effect, and the like.

Plant-derived extracts include, for example, tripterygium root extract, Polygonum cuspidatum root extract, Huangcen extract, licorice root extract, tea leaf extract, chamomile flower extract, rosemary leaf extract, soybean seed extract Wait.

[I agent] In the range that does not impair the effect of the present invention, other ingredients such as water, ethanol, glycerin, dipropylene glycol, PCA isostearic acid PEG-40 hydrogenated castor oil, gelatin, and coconut oil glutamine may be appropriately blended. Acid TEA salt, sodium lauryl dipropionate, alanine, glycine, arginine, sodium EDTA-2, phenoxyethanol, propyl parahydroxybenzoate, methyl parahydroxybenzoate, perfume, etc.

According to the hair treatment method of Embodiment 1, the effect of improving the treatment agent X selected from the group consisting of a hair coloring agent, a bleaching agent, a perm agent, a natural curly hair correcting agent, and a hair conditioner can be achieved while suppressing hair damage and repairing.

In addition, in the hair treatment method according to the first embodiment, the effect of shortening the treatment time of the treatment agent X can also be obtained by applying the [I agent] in the form of a foam.

2. Embodiment 2

FIG. 1 (B) shows a hair treatment method according to the second embodiment, which includes the first step of applying [I agent], and then applying a member selected from the group consisting of a hair dye, a bleach, a perm agent, a natural curl corrector, The second step of the treatment agent X of the hair conditioner further includes a third step of applying the [II agent].

Implementation mode 2 has a more excellent effect than implementation mode 1. Although the mechanism has not been explained, it is presumed that the treatment agent X also stayed on the surface of the hair by applying [I agent] at the beginning, so that the keratin and the like that supply nutrients to the hair contained in [I agent] remained on the hair surface. By coating [II agent] with coating [I agent] and treatment agent X, when the pH adjusting agent contained in [II agent] swells the hair, the [I agent] and treatment agent remaining on the hair surface are promoted together X penetrates into the inside of the hair. As described later in this specification, [II agent] is basic. In the art, substances that were previously considered to be generally alkaline would swell hair, and instead drain nutrients out of the hair. Therefore, after treating hair with an alkaline treatment agent X, it is common knowledge to neutralize hair acid-basic with an acidic conditioner or the like. However, according to the present invention, after treating hair with treatment agent X, by applying alkaline [II agent], while moisturizing the hair, it also inhibits the loss of nutrients in the hair to the outside of the hair, thereby suppressing and repairing When the hair is damaged, the effect of the treatment agent X can be improved.

In addition, keratin may be added in addition to the weight average molecular weight.

Furthermore, [II agent] contains a pH adjuster. The pH adjusting agent is not particularly limited as long as it can adjust the pH of the hair to weakly alkaline to alkaline. Arginine, which is a basic amino acid, is preferred. Since arginine is one of the amino acids originally contained in hair, it is not a burden on the hair and scalp, it can promote the supply of keratin, and it can also provide hair with moisturizing properties.

[II agent] is the same as [I agent], and it is more preferable to contain a foaming component. By containing a foaming component, [II agent] can be applied to hair in a foam form, and can be applied uniformly without omission, and can be efficiently applied to the entire hair with a small amount of application. In addition, by applying in a bubble form, the permeability of the [II agent] and the treatment agent X can be increased, and the effect of shortening the operation time can also be expected.

The foaming component is not particularly limited as long as it can make the [II agent] foamy. Anionic surfactants, cationic surfactants, zwitterionic surfactants, and nonionic surfactants can be used. From the viewpoint of compatibility of the other ingredients contained in the agent, a zwitterionic surfactant is preferred.

As long as the effect of the present invention is not impaired, other ingredients such as other ingredients and moisturizing ingredients may be appropriately blended in the [II agent].

Suitable moisturizing ingredients include betaine, urea, and sodium pyrrolidone carboxylate. The moisturizing component is not particularly limited, but it is preferable to include a plurality of moisturizing components from the viewpoint of achieving effective moisturizing. By achieving effective moisturization, the hair after the hair treatment of the present invention can enhance gloss, elasticity, moisturizing feeling, refreshing feeling, softness, and degree of treatment agent X effect.

[II agent] In a range that does not impair the effect of the present invention, other ingredients such as water, glycerin, dipropylene glycol, laurylamine propyl betaine, and sodium bis (laurylamine glutamic acid) lysine can be appropriately blended. , Phenoxyethanol, p-hydroxyl Methyl benzoate and the like.
