Problems solved by technology

From another point of view, when the content of hydrogen peroxide in the mixture is high, the damage to the hair and scalp increases; on the other hand, when the content of hydrogen peroxide in the mixture is small, the decolorization power cannot be improved, and the hair cannot be brightened. Can't improve dyeing power

Abstract

Provided is an oxidative hair dye that causes minimal scalp irritation and can reduce irritating odors during use, reduce damage to the scalp and hair, and sufficiently dye hair. This oxidative hair dye contains: a first agent, which includes (A) monoethanolamine or the like, (B) carbonate or the like, (C) ammonia, and (D) an oxidative dye; and a second agent, which includes (X) hydrogen peroxide. In the mixture of the first agent and the second agent, the content of (A) is 4.0-7.0 mass%, the content of (B) is 0.20-0.70 mmol / g, the total content of the ammonia and ammonium ions, in terms of ammonia, is 0.20-0.45 mmol / g, and the content of (X) is at least 1.5 mass% and less than 2.7 mass%.

Description

technical field [0001] The present invention relates to an oxidation hair dye comprising at least a first agent containing an alkaline agent and an oxidation dye, and a second agent containing hydrogen peroxide, wherein the first agent and the second agent are mixed and used. Moreover, this invention relates to the manufacturing method of the mixture for oxidation hair dyeing using an oxidation hair dye, and the method of oxidation hair dyeing. Background technique [0002] In order to dye hair, a multi-agent oxidation hair dye including a first agent containing an alkaline agent and an oxidation dye, and a second agent containing hydrogen peroxide is widely used. Hair is dyed using a mixture prepared by mixing the above-mentioned first agent and the above-mentioned second agent. [0003] When dyeing hair to a vivid color, bleaching power is often required. In addition, in the case of hair in which white hair and black hair are mixed, it is preferable to reduce the differe...
