Detailed Description

The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments. It is understood that these embodiments are given solely for the purpose of enabling those skilled in the art to better understand and to practice the invention, and are not intended to limit the scope of the invention in any way.

The Chinese hair is black, and the thick, black and moist hair can give people a vigorous and exciting feeling, so that people can glow and double the wind. However, thick and dark hair is not always seen by all people, and the incidence of canities is increasing in modern people.

According to the related art, experiments and mechanism researches aiming at different white hair people find that the color of the hair is mainly determined by the content of melanocytes and melanin in hair bulbs and hair papilla. Among them, melanocytes are mainly present in the epidermal basal layer and hair follicles. Tyrosinase is an important factor in determining melanin synthesis. The formation of white hair is often caused by a decrease in melanocytes and melanosomes, or a decrease in tyrosinase activity, which in turn causes melanin synthesis disorders.

Currently, melanin synthesis can be promoted to treat the white hair problem by activating the activity of tyrosinase and promoting the production of collagen.

The hair blackening agent provided by the embodiment of the disclosure can efficiently activate the tyrosinase, promote the spontaneous generation of the collagen to a normal level, further fundamentally improve the problem of white hair, and promote the white hair to naturally turn black.

In an exemplary embodiment of the present disclosure, the hair blackening agent may include the following components and weight percentages thereof:

the fructus Ligustri Lucidi peptide composition can include fructus Ligustri Lucidi high molecular peptide, fructus Ligustri Lucidi middle molecular peptide and fructus Ligustri Lucidi low molecular peptide. Promoting melanogenesis the first extract may be used to promote melanogenesis. In one embodiment, the first extract for promoting melanogenesis may include one or more of polygonum multiflorum extract, black mulberry extract, giant kelp extract and ganoderma atrum extract.

The fructus ligustri lucidi peptide composition comprises fructus ligustri lucidi high molecular peptide, fructus ligustri lucidi medium molecular peptide and fructus ligustri lucidi low molecular peptide, which can activate tyrosinase activity and promote collagen generation, thereby effectively promoting the natural blackening of white hair, and fundamentally solving the problem of white hair.

In the disclosed embodiment, the first extract for promoting melanogenesis and the extract of juglans sigillata can assist the glossy privet fruit peptide composition to activate the activity of tyrosinase and promote the generation of collagen on the one hand; on the other hand, the hair conditioner can nourish hair follicles and repair damaged hair scales so as to promote the hair to be smooth and moist.

In an exemplary embodiment of the present disclosure, the hair blackening agent may further include the following components and weight percentages thereof:

in the embodiment of the present disclosure, ethanol with an ethanol purity of 100% may be selected, and hydrous ethanol with a purity of less than 100% may also be selected, as long as the effective content of ethanol is finally ensured to be between 0.5% and 1%.

In one embodiment, 95% aqueous ethanol may be selected, and in this case, the 95% aqueous ethanol is present in an amount of 0.53% to 1.05% by weight of the hair blackening formulation.

In the embodiment of the disclosure, the addition of the cacumen biotae extract can further assist the glossy privet fruit peptide composition to activate the activity of tyrosinase and promote the generation of collagen, so that the natural blackening of white hair can be effectively promoted, and the problem of white hair can be fundamentally solved.

In another exemplary embodiment of the present disclosure, the hair blackening agent may further include the following components and weight percentages thereof:

the hair blackening agent provided by the embodiment of the disclosure can effectively activate the activity of tyrosinase and promote the generation of collagen through reasonable proportioning and based on the glossy privet fruit high molecular peptide, the glossy privet fruit medium molecular peptide and the glossy privet fruit low molecular peptide contained in the glossy privet fruit peptide composition, thereby promoting the natural blackening of white hair and fundamentally solving the problem of white hair.

Wherein the fructus Ligustri Lucidi peptide composition can be obtained by hydrolyzing fructus Ligustri Lucidi with enzyme or fermenting. The polypeptide (fructus Ligustri Lucidi peptide composition) of fructus Ligustri Lucidi can promote absorption via glycolipid, and effectively activate tyrosinase activity and promote collagen production, thereby promoting natural blackening of white hair.
