After statistics, the number of white hairs accounted for about 40% of the total number of hairs. The color of the white hairs was silver-white, forming a sharp contrast with the surrounding black hairs, which was very obvious visually and seriously affected his young appearance. In natural light, the white hairs reflected light significantly, making the whole hair look more aged. Duration of white hair appearance: Mr. Zhou stated that he accidentally found a few white hairs on the top of his head at about 18 years old and didn't pay attention at that time. In the following years, the number of white hairs gradually increased. By the age of 22, although it was only 4 years, the white hairs had developed to an uncontrollable level. During this period, Mr. Zhou tried a variety of products on the market that claimed to have the effect of turning white hairs black, but none of them achieved obvious results.
[0063] Treatment method: After hair cleaning and scalp massaging, apply 10 mL of the composition of Example 1 once a day to the white hair areas, covering the scalp and hair roots. Use the composition of Example 1 once every two days, and use it for a total of 30 days.
