The present invention relates to a hair dye composition containing, as an active ingredient, a natural ingredient and a carbohydrate, a carbohydrate derivative or a mixture thereof.

  A hair dye generally expresses color by causing an oxidative polymerization reaction between dyes contained in one agent by mixing one agent and two agents. Moreover, the melanin pigment | dye in hair is decomposed | disassembled with the hydrogen peroxide contained in 2 agents, and by decoloring hair, the ground color of hair can be lightened and a more vivid hue can be expressed.

  Since the dye used for the hair dye is small in size, it can enter the cortical layer of the hair, but if a polymer is formed by an oxidation reaction, it becomes difficult to enter the hair. Thus, if the polymerization reaction is caused before the dye penetrates into the hair and the molecular size is increased, the dyeability on the hair is lowered and the persistence after the dyeing is also lowered.

  In order to solve the above-mentioned problems, methods for improving dyeability and sustainability through methods such as adjusting the reactivity of dyes to improve penetration into hair have been proposed. As related techniques, Patent Document 1 “Hair dye composition for oxidative dyeing of keratin fibers containing gallic acid or an ester derivative thereof” and Patent Document 2 “Oxidative dyeing containing pentaploid or camellia grass” Hair dye ".
