DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a permanent wave method which is carried out when waving hair in a hairdressing salon or the like.

[0002]

2. Description of the Related Art Permanent wave has been known as a hair-making technique for forming a wave on hair by utilizing the reducing and oxidizing actions of a permanent agent. As a conventional permanent wave method, for example, first, FIG.
As shown in (A), the hair 1 is bundled, wound around a lot 2, and curled. Then, as shown in FIG. 7 (B), a reducing agent 4 as a first agent is applied to the hair 1 and left at room temperature. Or warm to reduce and soften the hair. Then lot 2
And confirming that the reduction reaction has proceeded sufficiently while observing the softening state of the hair. Thereafter, as shown in FIG. 7 (C), the oxidizing agent 5 as the second agent is applied to the hair 1. The hair is applied and left for a predetermined time to fix the curl on the hair.

In the operation of curling the hair 1 into the lot 2, it is common to wrap the hair end of the hair bundle with the end paper 6 and start winding from this part. In addition, as for the operation of applying the reducing agent, as shown in FIG. 7B, it is general that a chemical solution adjusted to a predetermined concentration is impregnated into the hair bundle using the applicator 6.

However, according to such a conventional permanent wave method, there are the following problems. Since the reducing agent is applied after the hair is wound around the lot, it is difficult to confirm whether an appropriate amount of the reducing agent is applied to the entire hair. Therefore, it is difficult to determine the amount of the reducing agent applied, and it is easy for unevenness to occur in the reduced hair. At the tip of the hair, the reducing agent easily penetrates and accumulates in the end paper, causing an overreaction in this portion, and the tip of the hair tends to stick. As shown in FIG. 8, when the hair 1 is wound around the lot 2, cracks 8 and distortions 9 are likely to occur in the hair epidermis of the hair 1, which may damage the hair or cause the hair to have its own gloss and smoothness. Easy to lose. Furthermore, when a reducing agent is applied to the hair, as shown in FIG. 4, the scale portion of the hair epidermis 18 is spread out, so that protein components inside flow out of the gap between the scales and easily damage the hair. It has become.

On the other hand, JP-A-63-194604 discloses
Turns the hair into reduced hair before the lot winding,
It is disclosed that a lot is wound after washing with water.
In the case of, after reducing hair is wrapped around the lot,
A step of applying and leaving it. That is,
Do not replenish the reduction reaction of the hair with a chemical after winding
Can not form a strong and persistent wave
No.

The present invention has been made in order to solve such problems, and an object of the present invention is to make it easy to adjust the amount of a reducing agent to be applied, and to make a lot winding so that the hair is not hurt. It is an object of the present invention to provide a permanent wave method which makes it possible to form a strong wave having good durability.

[0007]

In order to solve the above-mentioned problems, a permanent wave method according to the present invention is characterized by including the following steps (A) to (D). (A) A reducing agent is applied to hair, and the hair is left until it becomes soft and plastic (primary reduced hair). (B) The reducing agent attached to the hair (primary reduced hair) is washed away with water. (C) The hair (primary reduced hair) is bundled, wound around a lot , and heated in a wet state without drying, and
Make the bundle harden along the circumference of the lot (secondary reduced hair)
You. (D) An oxidizing agent is applied to the hair (secondary reduced hair), and the hair is left until a wave is fixed on the hair. Further, the permanent wave method according to the present invention comprises the step (C).
It is characterized in that the heating temperature is about 55 ° C.

[0008]

According to the permanent wave method of the present invention,
When applying the reducing agent to the hair, the operation can be performed by directly checking the applied amount of the reducing agent from the root to the tip of the hair. For this reason, it is easy to adjust the amount of the reducing agent applied to the entire hair. In addition, the permanent wave method of the present invention performs lot winding in a state of relatively soft primary reduced hair. At this time, as shown in FIG. 5, the primary reduced hair has a hair epidermis in an elastic and soft state. Furthermore, since the reducing agent attached to the primary reduced hair is washed with water before the work of winding the lot, it is possible to suppress the damage of the hair such as creaking due to the overreaction of the reducing agent, and to prevent the practitioner from winding the lot. It is easy to operate, and it is hard to damage fingers.

Further, when the reducing agent is applied to the hair, as shown in FIG. 3, the hair is kept in a natural and straight state. Therefore, the scale portion of the hair epidermis 18 closes to prevent the protein component from flowing out from inside the hair.

[0010] In the permanent wave method of the present invention, the primary reduced hair is wound around a lot and then heated to be changed into the secondary reduced hair. That is, the reducing agent remaining inside the primary reduced hair is activated to supplement the reducing reaction.
Thereby, the hair (primary reduced hair) was wound around the lot.
Later, the reduction reaction is supplemented without applying the reducing agent again
It is hard to damage hair and has good durability
Can be formed.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a process chart of the permanent wave method according to the present invention. After the hair diagnosis, first, Fig. 1
As shown in (A), the hair 10 is straightened and the reducing agent 12 is applied.

The amount of the reducing agent 12 applied is appropriately adjusted according to the length and position of the hair. For example, if more reducing agent is applied to the root of the hair, the wave at the root becomes stronger, and the durability of the wave is improved. Further, when there is a damaged portion in the hair, by applying a small amount of a reducing agent to this portion, the damage to the hair can be reduced.
As a method of applying the reducing agent 12, for example, it is preferable to apply the reducing agent to the surface of the hair with a brush or the like while combing the hair with a comb. Also, the hair may be directly sprayed with a sprayer.

Next, the whole hair is wrapped with a vinyl cap and left for a predetermined time. The leaving time is about 5 to 30 minutes depending on the hair quality and the like. Regarding the determination of whether or not the primary reduced hair has become, the surface of the hair becomes soft,
When a soft and plastic state is reached (a state in which the elasticity of the hair has almost disappeared), it is determined that the primary reduced hair has become.

As the reducing agent 12, for example, a reducing agent for cold perm, such as ammonium thioglycolate, may be used. In particular, it is preferable to use one containing a free ammonia-based alkali agent.

Thereafter, as shown in FIG.
Rinse off the reducing agent adhering to the well with water. At this time, a rinsing agent may be applied.

Next, the hair 10 is wound around the lot 13 as shown in FIG. For the winding operation,
The bristle tips are wrapped with end paper 14 and wrapped around the lot 13 and fixed with a rubber band or the like so that the lot does not come off the bristle bundle. At this time, if the primary reduced hairs come into contact with air for a long time, air oxidation occurs and it becomes difficult to fix the curl at the time of secondary reduction, so it is important not to dry the hair 10. After the curling operation, wrap the hair with a vinyl cap 7 to prevent drying.

Next, as shown in FIG. 2D, the hair (primary reduced hair) is heated from above the vinyl cap 16 by a heater 5 such as a far-infrared lamp. The set temperature of the heater 5 is set so that the surface temperature of the hair bundle wound in the lot is about 55 ° C. About heating time, hair length,
Set in consideration of hair quality. For example, for short hair, it may be about 10 minutes, and for long hair, it may be about 30 minutes.

At the end of the heating, it is assumed that the hair has hardened along the peripheral surface of the lot (secondary reduced hair).
As a criterion for determining whether or not the secondary reduced hair has been formed, for example, it can be determined that the secondary reduction has been completed when heat is transmitted to the hair tips. For example, when the palm is applied to the surface of the lot, if there is no change in the temperature between the lot and the hair bundle, it can be understood that heat is sufficiently transmitted to the hair tips. When the heat is not transmitted to the hair tips, the temperature of the lot and the hair bundle decreases because the inside of the lot is at a low temperature. It is also possible to release the part of the lot at regular time intervals while checking the degree of curl fixing.

Here, as shown in FIG. 6, the desired size of the curl diameter R can be set by using a lot having a diameter of about ／ of the R, and the curl strength R Can be up to 2 × W = R. If you want to increase the hair bundle surface temperature during heating to about 60 ° C, the size of W approaches R. If you want to weaken it, decrease it to about 50 ° C, and the size of W becomes W <R. . By lengthening the heating time as the hair becomes longer, it becomes possible to strongly form a curl up to the tip of the hair. In this manner, the desired curl intensity and size can be freely adjusted by the lot thickness and the total amount of heat by heating.

Next, the vinyl cap 16 is removed, and as shown in FIG. 2 (E), the oxidizing agent 17 is applied to the hair and left for a predetermined time to fix the wave on the hair. The application of the oxidizing agent 17 impregnates the drug solution into the entire hair with an applicator or the like. As the oxidizing agent, for example, a sodium bromate-based or hydrogen peroxide-based oxidizing agent may be used. afterwards,
The lot 13 is removed from the hair, the hair is washed with water, dried, and the operation is completed.

[0021]

As described above, according to the permanent wave method of the present invention, the following excellent effects can be obtained. (A) Since the application amount of the reducing agent is easily adjusted, the degree of wave application can be adjusted according to the length and position of the hair. (B) Distortion and cracks are less likely to occur in hair when wound in a lot, and a natural wave can be formed without impairing the gloss and smoothness inherent in hair. (C) Since the reducing agent adhering to the hair is washed off before the work of winding the lot, the operation of the practitioner becomes easy and the hand skin is not roughened. (D) Since the reduction reaction is performed in two stages, a strong and strong wave can be formed. (E) When the oxidizing agent is applied to the hair, no other chemical solution adheres to the hair surface, so that the chemical solution can be easily spread over the entire hair, and the wave fixing time can be shortened. (F) Since the reducing agent does not permeate into the end paper, it is possible to prevent the hair tips from sticking due to overreaction.
