Abstract

The invention relates to a hair dye, in particular to a natural hair dye prepared by using phytochrome curcumin and a hair dyeing method of the natural hair dye. The hair dye comprises an agent A and an agent B, and is characterized in that: the agent A contains 0.1 to 10 weight percent of curcumin, 20 to 50 weight percent of polyol, 1 to 5 weight percent of thickening agent, 1 to 10 weight percent of surfactant and the balance of water, and the pH value is regulated to be 3 to 7; and the agent B contains 1 to 10 weight percent of metal ion mordant, 1 to 5 weight percent of thickening agent, 1 to 10 weight percent of surfactant, 0.1 to 0.3 weight percent of natural essence and the balance of water, and the pH value is regulated to be 3 to 7. The hair dyeing method comprises the following steps of: uniformly spreading the agent A on the hair when the hair is dyed, and dyeing the hair for 10 to 40min at the temperature of between normal temperature and 60 DEG C; and uniformly spreading the agent B on the hair, mordanting for 10 to 20min, cleaning the hair and blow-drying. The curcumin has a good dyeing effect and also has the effects of resisting bacteria and protecting skin. Reagents which are toxic to human bodies are not used in the hair dye, and substances which are toxic to the human bodies are also not generated in the hair dyeing process, so the hair dye is high in safety. The adopted curcumin is insoluble in water and cannot fall off easily in the washing process, so the hair dye has a good dyeing effect, and the color of the dyed hair can be kept for a long time.

Description

technical field [0001] The invention relates to a hair dye, in particular to a natural hair dye using oil-soluble curcumin as a single-component plant pigment and a hair dyeing method thereof. Background technique [0002] Most of the hair dyes currently on the market contain p-phenylenediamine, p-aminophenol, hydroquinone, etc. Long-term use can lead to various diseases, such as hair loss, skin allergies, skin cancer, and malignant tumors. With the gradual improvement of people's health awareness and the continuous progress of beauty science, hair dyes prepared from natural plant pigments have increasingly become the development trend of the future hair dye market. In the existing patents, the main pigments of plant hair dyes include quercetin, hematoxylin, catechin and the like. The main problem that the existing plant hair dye exists is that the dye uptake rate of the hair dye is low and the color fastness is poor. [0003] As a natural pigment, curcumin is a chemical c...
