Abstract

Provided is a hair dye composition which suppresses dyeing affinity with skin, despite having sufficient dyeing affinity with hair. The hair dye composition includes: component A, namely basic blue 124; component B, namely at least one dye selected from the group consisting of basic orange 31, basic red 51, basic red 76, basic yellow 87, and basic yellow 57; component C, namely HC blue 2; and component D, namely at least one dye selected from the group consisting of HC yellow 4 and HC yellow 2. It is preferable that the content of component A be 0.005-0.5 mass%, the content of component B be 0.005-1.5 mass%, the content of component C be 0.1-1.5 mass%, and the content of component D be 0.01-0.5 mass%.

Description

technical field [0001] This invention relates to hair coloring compositions. This application claims priority from Japanese Patent Application No. 2017-066453 filed in Japan on March 29, 2017, the contents of which are incorporated herein by reference. Background technique [0002] Heretofore, as treatment agents for dyeing hair such as gray hair dyes and fashion hair dyes, the following oxidative hair dyes, etc., are commonly used. Consists of 2 doses. However, these oxidative hair dyes exhibit excellent dyeing effects and can dye desired hair color, but on the other hand, they have a disadvantage of causing damage to hair and scalp. In addition, it is necessary to leave the drug on the hair and leave it for a long time during handling, so it is very time-consuming to perform the treatment by yourself, and there are also disadvantages such as a pungent smell of an alkaline agent and skin irritation. In addition, depending on the means of operation, uneven dyeing results ...
