Abstract

The invention discloses a polymer amine-based hair dye and preparation and use methods thereof. The hair dye is prepared from an agent A and an agent B; the agent A is prepared from 5,6-dihydroxyindole, cetearyl alcohol, oleic acid, propylene glycol, isopropanol, sodium dodecyl sulfate, polymer amine, ammonium hydroxide and water; the agent B is prepared from hydrogen peroxide, oleyl alcohol, oleic acid, propylene glycol, isopropanol, sodium dodecyl sulfate and phosphoric acid. The preparation method comprises the steps that the agent A is prepared at first, and then the agent B is prepared. The use method comprises the steps that the agent A and the agent B are mixed at the proportion of 1:1, stirred to be uniform and then applied to hair, and then the hair is washed after 30 minutes. Accordingly, 5,6-dihydroxyindole in the hair dye is not likely to be oxidized in the air and easy to store, the dyeing effect is very obvious, the dye can enter the medulla of the hair, and when people wash the hair after dyeing, fading is not likely to occur.

Description

technical field [0001] The invention relates to the technical field of hair dyeing, in particular to a polymer amine-based hair dye and a preparation and use method thereof. Background technique [0002] Hair dye is a kind of cosmetics for dyeing hair. Chinese people belong to the yellow race, and it is more beautiful to dye white hair black, so black hair dye is very important. [0003] Hair dyes generally contain p-phenylenediamine, a carcinogen. Studies have shown that hair is composed of epidermal scale layer, cortex layer, and medulla layer. The epidermal scale layer is the outermost layer of hair, which is usually translucent or colorless. The natural hair color is revealed; the cortex layer accounts for 80% of the hair, and the natural pigment synthesized by the human body, that is, melanin, is deposited here. Due to the difference in the amount of melanin deposition, different hair colors appear; the medulla layer is located in the center of the hair and consists of ...
