Description

  The present invention relates to a hair deforming agent that imparts softness to the treated hair and can improve the unitization of the hair ends.

  In general, hair deforming agents such as permanent wave agents and hair straightening agents are composed of a first agent containing a reducing agent and a second agent containing an oxidizing agent.

  When hair is treated with the above-mentioned hair deforming agent, first, the disulfide bond in the hair is cleaved by the first reducing agent, and then the disulfide bond cleaved by the reducing agent by the second oxidizing agent is regenerated. The desired hair shape is formed.

  However, when the hair deformation treatment is performed by the mechanism as described above, since the hair is damaged because it involves the cleavage of disulfide bonds, the hair feels harder after treatment, and the damaged hair tip portion. However, there was a disadvantage that the spread spread and the unity became worse.

  Therefore, in order to eliminate the above-mentioned drawbacks in hair deforming agents, a technique has been proposed in which hair hydrolysates are blended with protein hydrolysates, cationic polymers, etc. to suppress damage to the treated hair (patent) Literatures 1-2).

  By the way, in recent years, hair color treatments are repeatedly applied to hair, and styling methods using heat such as hot curlers, hair irons, and dryers are often used. The degree of damage is easily different from the tip of the hair.

  If the hair with non-uniform damage degree is subjected to a deformation treatment using the hair deforming agent as described above, the softness of the hair may be impaired, or the hair tip part with a high degree of damage. Then, since it is in the state which is easy to react excessively with respect to a hair deformation agent, it exists in the tendency for a hair tip to stick or spread.

  The hair treatment agents disclosed in Patent Document 1 and Patent Document 2 have some functions to impart softness to the hair and improve the unitization of the hair tips when hair with a non-uniform damage degree is treated for each part. Have.
