Abstract

PROBLEM TO BE SOLVED: To enable hair to be set quickly, easily, and securely by giving solution of a substance containing a mercapto group to hair. SOLUTION: When ultrasonic vibration is given to hair 2 to set the hair 2 using a hair setter 4, solution of a substance containing a mercapto group is given to the hair 2. As a substance containing a mercapto group, the protein component contained in the hair 2 can be preferably used, for instance, cysteine can be used. Mercaptobenzoic acid also can be used. The solution of a substance containing a mercapto group can be given, for instance, by applying the solution to the hair 2. It is allowed to give ultrasonic vibration to the hair 2 after applying the solution to the hair 2, or otherwise to apply the solution of a substance containing a mercapto group giving ultrasonic vibration to the hair 2. After drying the hair 2 applied with the solution of a substance containing a mercapto group, ultrasonic vibration can be given to the hair 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair setting method using ultrasonic vibration.

[0002]

2. Description of the Related Art A hair setting method using a two-pack permanent is:
Cleavage of cystine bond (SS bond) in hair by first agent, rinsing of first agent, cystine recombination by second agent,
This is performed by the procedure of washing off the second agent, and it takes a considerable amount of time to set the hair.
In addition, the first agent having a high pH value causes a large damage to the hair, and if the recombination by the second agent is insufficient, the SS bond remains broken, so that the damage due to protein denaturation is also large. Become.

[0003] A hair hair setting method using ultrasonic vibration in addition to such a perm solution is also disclosed in US Patent No.
No. 9 and the like.

[0004]

However, the damage to hair is still large. It has also been proposed to set the hair by applying only ultrasonic vibration to the hair, but in this case, the hair is easily damaged.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hair setting method which can set easily and securely in a short time and which is gentle on hair. It is in.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a method for setting a hair, such as bending or stretching the hair, by bringing the hair into contact with a vibrating body that vibrates in the ultrasonic range. Is applied to the hair.

[0007] By applying a solution of a substance containing a mercapto group to the hair, it is easy on the hair and the setting property is improved.

Applying a solution of a substance containing a mercapto group to hair involves applying a solution of a substance containing a mercapto group to hair while applying ultrasonic vibration to hair, and applying a solution of a substance containing a mercapto group to hair. After applying and drying the solution,
After applying ultrasonic vibration to the hair or applying a solution of a substance containing a mercapto group to the hair and drying, apply water to the hair, and then apply ultrasonic vibration to the hair, or apply mercapto to the hair. After applying and drying the solution of the substance containing the group, the solution of the substance containing the mercapto group is again applied to the hair, and thereafter, ultrasonic vibration is applied to the hair, and further, the substance containing the mercapto group is added to the hair. After applying and permeating the above solution, washing and drying, the hair may be subjected to ultrasonic vibration.

The substance containing a mercapto group can be selected from protein components present in the hair, and for example, cysteine can be used.

Further, as a substance containing a mercapto group, mercaptobenzoic acid can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment. FIG. 1 shows an example of an ultrasonic hair setting device 4 used in the present invention. The circuit, 30 is an ultrasonic vibrator, 31 is an ultrasonic horn, and a hair contact portion 1 that contacts the hair 2 (the hair 2 is wound around) is connected to the ultrasonic horn 31. The vibrator 30 driven by the drive circuit 3 and vibrating in the ultrasonic region transmits the vibration to the hair contact portion 1 via the ultrasonic horn 31 and the ultrasonic wave is transmitted to the hair 2 contacting the hair contact portion 1. Apply vibration. The ultrasonic hair setting device 4 that can be used in the present invention is not limited to the one shown in the illustrated example for curling the hair. For example, the ultrasonic hair vibrator 1 directly contacts the hair contact portion 2.
May be stuck to the hair to perform straight setting.

In the present invention, a solution of a substance containing a mercapto group (SH group) is applied to the hair when setting the hair by applying ultrasonic vibration to the hair using a hair setting device as shown in the drawing. You do it. As the substance containing a mercapto group (SH group), a protein component contained in hair can be suitably used, and for example, cysteine can be suitably used. Mercaptobenzoic acid may be used. Applying a solution of a substance containing a mercapto group to hair may be performed, for example, by applying the above solution to hair, but in addition to applying ultrasonic vibration to hair after applying the above solution to hair, A solution of a substance containing a mercapto group may be applied to hair while applying ultrasonic vibration.

Further, after applying a solution of a substance containing a mercapto group to the hair and drying it, ultrasonic vibration may be applied to the hair. The ultrasonic wave application time can be shortened and it is electrically safe.

After applying a solution of a substance containing a mercapto group to the hair and drying the solution, water may be applied to the hair, and thereafter, ultrasonic vibration may be applied to the hair. In addition to easy control of the hair setting, the effect of preventing overheating due to water can be obtained.

When a solution of a substance containing a mercapto group is applied to hair and dried, then a solution of a substance containing a mercapto group is applied again to the hair, and thereafter, when ultrasonic vibration is applied to the hair, The set effect can be increased.

Further, after applying and permeating a solution of a substance containing a mercapto group to the hair, washing and drying the hair, ultrasonic vibration may be applied to the hair. Hair damage due to excess agent and hair damage due to friction with the precipitate can be prevented.

In any case, when a solution of a substance containing a mercapto group is applied to the hair, it is of course easier to use the hair than when the hair is set by applying only ultrasonic vibration to the hair. Compared with the case where a sexual perm is used, a quick and quick hair setting is possible, and a strong hair setting can be performed by applying a solution of a substance containing a mercapto group to hair a plurality of times.

When protein components in the hair are used, for example, when cysteine having a pH substantially equal to that of the hair is used, the cysteine is easily used by the hair, so that the hair becomes easier and the health of the hair is enhanced. It also becomes something.

Mercaptobenzoic acid may be used. In this case, the reaction in which the SH group becomes an SS bond in the hair proceeds, and the durability of the hair set is further increased.

[0020]

As described above, in the present invention, not only the case where a two-pack permanent is used but also the case where the hair is gentler than the case where the hair is set by applying only ultrasonic vibration. The setting can be performed, and since only one agent is applied and the ultrasonic vibration is applied, the hair can be set easily and speedily, and the hair can be surely set.
