Description

  The present invention relates to a method for treating wave-permitted hair.

  As a means for setting the hair in a desired shape over several weeks to several months, for example, wave perm treatment is known. In normal wave perm treatment, the first agent containing a reducing substance such as thioglycolate or cysteine cleaves the cystine bond inherent in the hair and relieves stress generated when the hair is deformed. Subsequently, the cystine bond is reformed by the second agent containing an oxidizing substance such as bromate and hydrogen peroxide to recover the stress and fix it in a desired shape. The shape imparting to the hair is performed by winding the hair around a rod or the like before and after application of the first agent.

  However, after several days to a week have passed after the wave perm treatment, the shape imparted by the wave perm treatment gradually loosens. In order to restore the looseness, wave perm processing is performed again. However, if the wave perm processing is repeated frequently, damage to the hair becomes severe, so the processing interval is about one month. In addition, if the treatment is applied strongly to maintain the shape until the next wave perm treatment, damage to the hair will also become severe, so there is a limit in how to cope with the strength of the treatment.

  In the case of treating both wave perm and hair coloring on the hair, it is generally recommended to leave an interval of about one week before and after from the viewpoint of preventing damage to the hair. At this time, it is common to perform the hair perm treatment first and then the hair dyeing treatment. This is to prevent the hair coloring process from being performed, because the color previously applied to the hair is lost during the subsequent wave permanent process.

  On the other hand, if the wave perm treatment is performed first and then the hair dyeing process is performed, the wave becomes loose during the hair dyeing process. In particular, from the viewpoint of preventing damage to the hair, loosening of the waves becomes remarkable when a certain period is provided from the wave perm treatment to the hair dyeing treatment.

  For this reason, there is a demand for a treatment method that can improve the durability of wave perm for hair damaged by wave perm treatment and can suppress loosening of the wave during hair dyeing for hair after wave perm treatment. It was.

  It should be noted that there is no prior art document information related to a hair treatment method for suppressing wave loosening.

  Therefore, the subject of this invention is providing the processing method which can suppress the loosening of a wave with respect to the hair by which wave perm processing was carried out.

  The present invention relates to a hair treatment method (hereinafter referred to as hair treatment) in which wave-perm-treated hair is treated with a composition containing the following components (a) 0.1 to 20% by mass and (b) 0.01 to 5% by mass. , "First hair treatment method").

  In addition, the present invention is to sequentially or simultaneously perform the processing by the following component (a) and the processing by the component (b) on the hair before or after the wave perm processing, or after the wave perm processing. The present invention provides a hair treatment method (hereinafter referred to as “second hair treatment method”).

  Component (a): Aromatic sulfone compound represented by the following general formula (1)

[In the formula, R is the same or different and represents a hydrogen atom or a monovalent hydrocarbon group, or a saturated or unsaturated divalent hydrocarbon group formed by combining two adjacent Rs together.
