Description

  The present invention relates to a hair treatment agent that is used after hair reduction treatment in hair deformation treatment such as wave formation and curly hair straightening, and adjusts the hair oxidation environment.

  In the hair deformation treatment accompanied by the hair reduction treatment represented by the permanent wave treatment and the straight permanent treatment, the hair is oxidized after the reduction treatment to fix the deformation.

  If the oxidation at this time is insufficient or non-uniform, the effect of the hair deformation treatment cannot be sufficiently obtained, and a good finish feeling cannot be obtained.

  For such problems, conventionally, after reduction treatment, treatment prior to oxidation with an intermediate acid rinse of pH 3-6 (for example, Non-Patent Document 1), bromate-type oxidation treatment agent of pH 5-7, Alternatively, a hydrogen peroxide type oxidation treatment agent having a pH of 2 to 4 has been used. However, these hair treatment agents according to the prior art are not sufficiently or uniform in oxidation effect and are strongly required to be improved.
