CONSTITUTION:The coloring and perming agent is obtained by combining a perming first agent containing a reducing agent such as thioglycolic acid with a perming second agent containing an oxidizing agent such as sodium bromate and L-tyrosine and an additive for the perming second agent containing tyrosinase. The tyrosinase for additive is preferably blended so as to give >=100ml/1000 units when mixed with the perming second agent. Furthermore, a method for treating hair with the perming first agent, washing the first agent and treating the hair with a mixture of the perming second agent and the additive is preferably used. This method is free from dyeing to head skin in perming and coloring and can dye hair containing white hair into natural color which hair itself has so as not to make white hair prominent.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a permanent wave treatment or a hair straightening treatment (hereinafter, these treatments may be collectively referred to as a "perm treatment") for hair containing white hair.
At the same time, the coloring of the melanin pigment, which is originally performed in the hair roots in the body, is performed in the hair, so that the gray hair is dyed in the natural color shade of the hair, making the hair inconspicuous. The present invention relates to a coloring perm agent and a coloring perm method using the same.

[0002]

2. Description of the Related Art The current mainstream of coloring (hair dyeing) is a first hair dye containing a diamine-based oxidative dye such as paraphenylenediamine and a second hair dye containing an oxidizing agent such as hydrogen peroxide. It is a permanent hair dye that is mixed just before dyeing and is applied to the hair, and the oxidation dye undergoes a poly (condensation) reaction in the hair to form a macromolecule, which is changed into a sparingly soluble dye to color the hair.

Conventional hair dyes containing such diamine-based oxidative dyes have excellent fastness to washing, but are highly toxic such as contact dermatitis, and use of hydrogen peroxide damages hair. There was a problem such as large. Therefore, in order to alleviate these drawbacks, it has been necessary to consider at least one week after the permanent wave treatment when performing the coloring treatment.

On the other hand, as a temporary hair dyeing method, there is a method of coloring with a hair dye containing an acid dye utilizing ion dyeing. However, it is easy to dye the scalp during the treatment and the dye drops every time the hair is washed. There was a problem. Further, there is a method of performing treatment with a mixture of a sulfite-based coloring agent or a sulfite-based straightening agent and an acid dye in order to perform perm and coloring at the same time. However, this method has a very weak effect of coloring and straightening force, and it is not different from simply coloring with an acid dye-based hair dye, and it also stains the scalp during treatment. Easy,
The problem that the dye drops every time the hair was washed was not solved.

[0005]

SUMMARY OF THE INVENTION The present invention has been made paying attention to the drawbacks of these conventional hair dyes and the drawbacks of combined treatment of perm treatment such as permanent wave treatment or curly straightening treatment and coloring treatment. It does not impair the wave forming function and hair straightening function, does not stain the scalp during the treatment, has excellent wash fastness, and dyes the gray hair in its original natural shade to make the gray hair inconspicuous Aimed to do so.

[0006]

The object of the present invention is as follows.
A perm first agent containing a reducing agent, a perm second agent containing an oxidizing agent and L-tyrosine, and a perm second agent containing tyrosinase
This can be achieved by using a coloring / perming agent characterized by being combined with an additive for the agent.

Further, a first step of treating the hair with the above-mentioned first permanent agent, and a second step of washing the first agent with water.
The third step of treating the hair with the mixture of the second permanent agent and the second additive for the second permanent agent is sequentially carried out, and the hair is colored at the same time as the permanent wave treatment or the straightening treatment. A preferable result can be obtained by a coloring / perm method in which a ring operation is performed.

The reducing agent used in the first permanent agent of the present invention comprises one or more selected from thioglycolic acid, thioglycolate, cysteine and acetylcysteine. The acid salt may be ammonium thioglycolate, sodium thioglycolate, potassium thioglycolate, monoethanolamine thioglycolic acid, triethanolamine thioglycolic acid, or the like.

The compounding amount of the reducing agent in the first permanent agent is preferably in the range of 2 to 11%. If it is less than 2%, the wave-forming power and curly straightening force are not sufficient, and if it exceeds 11%, damage to the hair becomes large. The pH of the first permanent agent is preferably in the range of 4-10. Outside this range, hair and skin damage is increased.

The oxidizing agent used in the second permanent agent of the present invention is preferably a bromate such as sodium bromate or potassium bromate. The use of hydrogen peroxide has the drawback that the melanin synthesis reaction is difficult to proceed. Further, the blending amount of bromate is preferably within the range of 1 to 10%.

The amount of tyrosinase used as the additive for the second permanent agent in the present invention is preferably 1000 units / 100 ml or more when mixed with the second permanent agent.

The first perm agent and the second perm in the present invention
Agents and additives for the second permanent agent, if necessary, other components within a range that does not impair the effects of the present invention,
For example, cationic or anionic, amphoteric or nonionic high molecular or low molecular surfactants, urea, higher alcohols, protein hydrolysates, amino acids, hair restorers, preservatives, acid dyes, basic dyes, pH A regulator, a fragrance, a natural pigment, purified water and the like can be added and blended.

[0013]

According to the present invention, since the perm first agent containing the curling or straightening reducing agent and the perm second agent containing the oxidizing agent are used in combination, a strong curling force for hair or Straight force works. Also L
-By using the perm second agent containing tyrosine and the perm second agent additive containing tyrosinase at the same time in the intermediate step of hair treatment, dyeing to the scalp does not occur during the treatment, and the natural hair color is obtained. You can dye gray hair to make gray hair inconspicuous. Also, the hair has excellent fastness to washing.
