Description

  The present invention relates to a hair dye cosmetic comprising a non-oxidative hair dye and a hair dye containing HC dye, and a hair dyeing method using the same.

  A permanent hair dye is a hair dyeing cosmetic that gives a permanent dyeing result to hair. As a permanent hair dye, conventionally, a first agent containing an oxidative dye such as paraphenylenediamine and an alkali agent and a second agent containing an oxidant such as hydrogen peroxide are used in combination. Hair dyes are generally widely used. However, the oxidized hair dye may damage the hair due to the action of the alkaline agent and the hydrogen peroxide solution. Some oxidative dyes can also cause strong allergic reactions.

  In recent years, various types of non-oxidative hair dyes have been proposed in order to solve problems that may occur in such oxidized hair dyes. For example, the reaction of polyhydric phenols with metal salts. Hair dyes for hair dyeing are known (see Patent Documents 1 to 7). A photobleaching comprising a combination of a first agent containing a substance that develops color by reacting with iron, such as tannic acid, gallic acid and derivatives thereof, and a second agent containing an iron salt. A non-oxidative hair dye having a preventive effect has also been proposed (Patent Document 8). Furthermore, various hair dyes using HC dyes or basic dyes as dyes have been proposed (Patent Documents 9 to 11).

Japanese Patent Publication No. 48-31902 JP-A-53-52633 JP-A-55-154912 JP-A-62-33113 JP-A 64-90117 Japanese Patent Laid-Open No. 4-164017 JP-A-5-170629 JP 2011-126845 A JP 2013-95734 A JP 2014-101292 A JP 2012-246284 A

  However, both of the conventional non-oxidative hair dyes and hair dyes disclosed in the above-mentioned patent documents require a long time for hair dyeing or repeated hair dyeing. The hair dyeing effect, color tone and gray hair combing effect were not always satisfactory. In particular, when tannic acid, gallic acid and their derivatives are combined with iron salts, increasing the tint to sufficiently dye white hair tends to increase the bluish color of the hair after dyeing. It was difficult to give a fine finish.

  The object of the present invention is to prepare a natural hair color by adjusting the hair after dyeing, while having excellent hair dyeing effect and white hair combing effect without causing damage to the hair or allergic reaction. It is to provide a non-oxidative hair dyeing cosmetic that can give hair.
