Abstract

The invention discloses a single-dosage form air oxidation hair dye, a preparation method and a hair dyeing method, and relates to the field of hair dyeing products. The single-dosage form air oxidation hair dye is prepared by the following steps of: S1, adding carbomer into sterile water to obtain an initial solution; S2, adding an auxiliary agent into the initial solution, and mixing to obtain an intermediate solution; and S3, introducing nitrogen for anti-oxidation protection, and then adding a dye intermediate to obtain the hair dye. The nitrogen is adopted for anti-oxidation protection in the production process of the hair dye, and the hair dye does not contain oxidation components such as anti-oxidation components and hydrogen peroxide, so that the irritation and damage of an oxidizing agent to scalp and hair are avoided, the sensitization rate is reduced, and the smoothness of the hair is improved.

Description

Technical field [0001] The present invention relates to the field of hair color products, hair dyes and more particularly to a method of preparing a single dosage form and hair and air oxidation. Background technique [0002] Hair coloring can change the color and brightness, as well as enhance the beauty raise awareness of people's living standards, the hair has become an important option for those who have a healthy beautiful hair, hair products have become an integral part of people's daily life supplies. [0003] Traditional hair products currently on the market in accordance with the degree of staining firm mainly classified into three types: temporary hair dyes, semi-permanent and permanent hair dyes hair dyes, permanent hair dyes which are currently the most widely accepted by consumers of a class of products . Permanent hair dyes, also known as oxidative hair dye, a hair dye containing coloring material, almost all at least two electron-donating group in the ortho positio...
