HAIR DYEING/DE-DYEING KIT AND METHOD FOR DYEING/DE-DYEING HAIR

摘要

PROBLEM TO BE SOLVED: To provide a hair dyeing/de-dyeing kit and a method for dyeing/de-dyeing hair by which de-dyeing properties can be improved and reoxidation can be suppressed in the hair dyeing/de-dyeing kit and the method for dyeing/de-dyeing the hair.;SOLUTION: The hair dyeing/de-dyeing kit is composed of (A) an oxidation hair dye containing an oxidation dye and a de-dyeing agent containing (B) ascorbic acids and (C) at least one kind selected from a solvent and a surfactant. In the hair dyeing/de-dyeing kit, the octanol/water partition coefficient [log(P_OW)] of (A) the oxidation dye is within the range of +1.5 to -3.0 of the octanol/water partition coefficient of at least one kind selected from (C) the solvent and surfactant and 0.5-30.0 mass% of the component (C) is contained in the de-dyeing agent.;COPYRIGHT: (C)2008,JPO&INPIT
