Description

  The present invention relates to an oxidized hair treatment agent that can be used for decoloring hair and hair, and can impart a good gloss to the hair after treatment.

  An oxidized hair treatment agent such as an oxidized hair dye or a decoloring agent comprises a first agent containing an alkaline agent and a second agent containing an oxidizing agent such as hydrogen peroxide. These first agents And the second agent are mixed and applied to the hair. The mechanism by which the hair is discolored by such an oxidized hair treatment agent is as follows. When the oxidizing agent decolorizes (bleaches) by decomposing the melanin pigment in the hair, and further uses the oxidized hair dye, The oxidative dye introduced by being pre-blended with the agent is colored and dyed by oxidative polymerization in the hair.

  In such oxidized hair treatment agents, especially oxidation hair dyes, various cationic polymers have been studied for the purpose of improving dyeability, color fastness, and hair feel after treatment (Patent Documents). 1-3) and examination (patent documents 4-6) which mix | blend a fatty acid are made | formed.
