Problems solved by technology

[0011] In order to overcome the shortcomings of several permanent hair dyes currently on the market: the raw materials of common plant permanent hair dyes are limited, the dyeing color is less, and the fastness is not high; the metal dyes contained in metal permanent hair dyes cannot be oxidized Dyes and cold perm are used in combination, and many metal dyes are toxic; oxidative permanent hair dyes contain phenylenediamine, which has the risk of sensitization, teratogenicity, and carcinogenicity

Abstract

The invention relates to a hair dye and particularly relates to a natural durable hair dye prepared from iridoid and amino acid and a hair dyeing method. The hair dye provided by the invention contains an agent A, an agent B and an agent C, wherein the agent A contains 8-12% of amino acid, 1.0-5.0% of thickening agent, 0.5-1% of vitamin C and the balance of water, and the pH value of the agent A is adjusted to 8-10; the agent B contains 2-5% of iridoid, 1.0-5.0% of thickening agent, 2-4% of phenethyl alcohol and the balance of water; the agent C contains 3-12% of hydrogen peroxide, 1-5% of thickening agent and the balance of water. The hair dyeing method comprises the steps of firstly, discoloring hair, and then, washing and drying; then, uniformly coating the agent A on the hair, and keeping at the temperature of 30-35 DEG C for 15-25min; next, uniformly coating the agent B on the hair, and keeping at the temperature of 30-35 DEG C for 15-25min; finally, uniformly coating the agent C on the hair, keeping at the temperature of 30-35 DEG C for 20-25min, washing and drying the hair. No substances capable of generating toxicity to human bodies are generated in preparation and application processes of the hair dye; the hair dye is good in safety, capable of dyeing the air into various colors such as black, red, yellow, purplish red and the like, plentiful in dyed colors and favorable in fastness.

Description

1. Technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a natural permanent hair dye prepared from iridoids and amino acids as raw materials and a dyeing method thereof. 2. Background technology [0002] The current common permanent hair dyes are mainly divided into the following categories according to their ingredients: [0003] (1) Plant permanent hair dye: use organic substances extracted from the stems and leaves of plants for dyeing. But because the color and luster and the effect of its dyed hair are not satisfactory, and the available plant species and resources are limited, the price is expensive, and the application range is not wide. [0004] (2) Metal permanent hair dye: use metal raw materials for dyeing. The hair dyeing mechanism is that metal ions can reduce the disulfide bonds in the scalp keratin to produce black hair dyeing. Commonly used metal hair dye raw materials are lead acetate, lead ...
