Acidic hair dye and hair dyeing method thereof

Abstract

The invention discloses an acidic hair dye. The acidic hair dye is prepared from the following components by weight percent: 0.5 to 3 percent of cellulose thickening agent, 5 to 15 percent of cyclic ketone, 5 to 15 percent of aromatic alcohols, 0.01 to 1 percent of acidic dye, 0 to 1.5 percent of pH adjusting agent, 0 to 2 percent of additives, and the balance of water. The acidic hair dye has theadvantages of rapidness in coloring, good in coloring performance, high in washing color fastness, no irritation for skin and the like. The invention also discloses a coloring method of the hair dye.The coloring method has the characteristics of rapidness in coloring, good coloring performance, high washing color fastness, no irritation to the skin and the like.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an acidic hair dye and a hair dyeing method thereof. Background technique [0002] Acidic hair dyes are usually single-dose products, generally in the form of a cream with high viscosity. When using, squeeze out the cream and apply it directly to the hair, and the color can be applied evenly. As a semi-permanent hair dye, compared with oxidative hair dyes, no hydrogen peroxide is added, and it is only deposited on the surface of the hair. Compared with oxidative hair dyes, the toxicity is much lower and the damage to the hair is relatively small. As a single-dose type Cream products, which do not need to be mixed, are also convenient for consumers to use. However, acidic hair dyes have disadvantages such as color difference, poor color fixation, and easy fading after washing. It needs to be used many times to maintain a good coloring effect on the hair, which greatly restricts its a...

Problems solved by technology

However, acidic hair dyes have disadvantages such as color difference, poor color fixation, and easy fading after washing. It needs to be used many times to maintain a good coloring effect on the hair. Hair coloring products still favor oxidative hair dyes

[0003] Existing semi-permanent acidic hair dyes mostly use xanthan gum to thicken and use short-chain fatty alcohols such as ethanol as solvents, and the coloring and color fastness to washing are general; in order to obtain a good hair dyeing effect, some existing acidic hair dyes The pH value of its hair dye is adjusted to below 3.0 or even lower to 2.5, which will cause irritation to the user's scalp
