Hair dye for physically dyeing hair by using plant extracts and natural pigments and preparation method thereof

Abstract

The invention discloses a hair dye for physically dyeing hair by using plant extracts and natural pigments. The hair dye is prepared from mulberry leaves, natural carbon black, scutellaria baicalensis, fermented Pu'er tea, bletilla striata, scutellaria baicalensis, prepared fleece flower roots, and other raw materials. The invention also provides an application method of the hair dye. Hair scalesare opened through a mulberry leaf extract; natural carbon black is adsorbed on the hair scales and clamped between the hair scales; extract of scutellaria baicalensis and prepared fleece flower rootsare adopted to close the scales on the surface layer of hair, natural carbon black is firmly clamped in the scales of the hair, the color fastness of a chemical hair dye is achieved, the surface of the hair presents a smooth surface effect, very high scale-like brightness is generated, and the blackened hair becomes thick, black and shiny. The hair dye is prepared from natural raw materials, doesnot contain any chemical agent, is safe and non-toxic, does not injure hair and scalp, does not generate any side effect on human health, is a good product for pregnant women, patients and weak people, and has a good market application prospect.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to a hair dye and a preparation method for physically dyeing hair using plant extracts and natural pigments. Background technique [0002] With the gradual increase of silver-haired people and the change of people's aesthetic concept, the market demand for hair dyeing and color fixing products will increase day by day. With the continuous improvement of people's attention to health, chemically synthesized hair dyes contain carcinogenic and strong allergenic chemical dyeing ingredients (such as phenylenediamines, aminophenols, etc.) and some harmful ingredients (such as hydrogen peroxide, ammonia water, etc.) etc.), has received more and more attention. For this reason, people try to seek natural harmless, safer hair dyeing materials. For example, plant pigment hair dyes have achieved certain results, but there are still many problems. Such products still cannot avo...

Problems solved by technology

Among carbon-based dyeing black materials, carbon black has good colorability and chemical stability, is safe, non-toxic and low in price, and is widely used in fields such as rubber, plastics and coatings, and has also been reported in hair dyes. The black particle size is small and easy to agglomerate, and the polar groups on the surface are less suitable for wetting, so the dispersion stability is poor. There are problems such as uneven coloring and insufficient color fastness when dyeing black hair with it. Most of them are only used in temporary hair dyes or As a dyeing aid

If it can solve the problems of uneven coloring and insufficient color fastness of carbon black hair dye, it can be regarded as an ideal permanent black hair dye colorant
