Abstract

The invention provides a plant pigment hair coloring agent, a preparation method and a use method thereof. The plant pigment hair coloring agent, which comprises an agent A and an agent B, wherein theagent A comprises a plant penetrant extraction liquid, a softener, an oil phase, a preservative, an alkali agent and water, the agent B comprises a plant penetrant extraction liquid, a plant pigmentextraction liquid, a ferrous salt, an antioxidant, an oil phase, a preservative and water, the agent A is used for opening the hair keratin scales, and the agent B is used for dyeing with the plant pigment. According to the present invention, the mixed plant penetrants are respectively added to the agent A and the agent B, such that the softener or the plant pigment molecule is promoted to penetrate into the deep positions of the hair scales so as to achieve the firm and lasting dyeing; the plant pigment hair coloring agent has advantages of easy dyeing, lasting and stable hair color fixation,no fading, no toxicity and no irritating to the skin; and with the plant pigment hair coloring agent, only two coating and one washing are required to be performed during the hair coloring, such thatthe process is simple and rapid, and the plant pigment hair coloring agent is the real plant hair coloring product.

Description

technical field [0001] The invention belongs to the field of hair dyes, in particular, the invention relates to a plant pigment hair dye. The invention also relates to a preparation method and application method of the plant pigment hair dye. Background technique [0002] At present, the mainstream products of hair dyes on the market are chemical hair dyes, which use p-phenylenediamine or quinone and their derivatives in different proportions with other chemical components to oxidize with hydrogen peroxide to develop color. A number of studies have confirmed that oxidative dye hair dyes have certain damage to the scalp and are highly toxic, which can easily cause redness, swelling, tingling and other discomfort on the skin, and even cause cancer after long-term use. [0003] Although some plant hair dyes have also appeared on the market, under certain conditions, the polyphenols contained in plants react with ferrous salts to form black complexes, which can achieve the purp...

AI Technical Summary

Problems solved by technology

But existing plant hair coloring product still has the following deficiencies: the one, do not add the reagent that opens hair cuticle, comprise alkali agent, oxidizing agent, reductive agent etc., also do not add the auxiliary agent that opens hair cuticle, i.e. softening agent, for example application number is The patent of 201310709263.5 discloses a health-preserving herbal plant hair dye; the second is that no penetration-promoting agent is added, so that the pigment macromolecules cannot enter the deep part of the cuticle, resulting in poor coloring and insufficient color fastness. For example, the application number is 201010225971.8 The patent discloses a turmeric plant hair dye; the third is that the plant pigment and ferrous salt are separated into two agents, and the complex reaction of plant pigment and ferrous salt needs to be carried out on the hair, and the ferrous iron becomes trivalent after meeting alkali. The precipitation of iron will inevitably affect the entry of pigment into the cuticles, so the coloring effect is not good and the color fastness is not enough. For example, the patent application number 201611043567.2 discloses a natural plant hair dye; the fourth is that the hair dyeing process is complicated to operate, such as application number Patent 201010225971.8 discloses a turmeric plant hair dye
