DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair deforming agent capable of semi-permanently deforming hair without damaging the hair, and a hair deforming method using the same.

[0002]

2. Description of the Related Art Perm is a method of applying semi-permanent deformation to hair, such as applying a wave to straight hair or turning straight hair. This perm first cleaves the S--S bond of keratin protein in hair under alkaline conditions by applying a composition containing a reducing agent such as thioglycolic acid or cysteine to the hair, followed by sodium bromate or the like. Is applied to re-bond other S—S bonds to give the hair semi-permanent deformation.

[0003]

As described above, the hair setting mechanism by the reducing agent and the oxidizing agent used in the permanent is the cleavage and recombination of the SS bond of the keratin protein in the hair. The chemical treatment denatures the keratin proteins in the hair and weakens the hair structure. Such weakened hair is susceptible to physical external forces such as brushing, which is one of the causes of hair damage. However, conventionally, the only method that can permanently deform hair is perm treatment. Therefore, a method for semi-permanently deforming hair without damaging the hair has been desired.

Under such circumstances, the present inventors have conducted intensive studies and as a result, it has been found that the use of a composition containing a polyol enables the hair to be deformed semi-permanently without damaging the hair. And completed the present invention.
