Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of cosmetics, and particularly relates to a composition for promoting the blackening of gray hair on both temples, a preparation method thereof, and an application thereof. Background Art
[0002] With the increase of age, the scalp hair follicles are gradually damaged and atrophied, and the melanocytes decrease, resulting in gray hair. At the same time, due to physical weakness, high work pressure, and irregular life, adverse reactions occur in physiological functions, and the graying of hair at a younger age has become a common social phenomenon. With the development of the economy and the improvement of people's living standards, people pay more and more attention to the blackening of hair. People hope to have more choices of hair blackening products, especially the demand for functional subdivision, such as products for blackening the gray hair on the forehead, the gray hair on the back of the head, and the gray hair on both temples.
[0003] Looking at the hair blackening products, the current hair dyeing products on the market basically achieve the purpose of blackening hair by dyeing the already grown hair. Its disadvantage is that the permanence is not absolutely lasting. Since hair grows every day, although the color tone of the dyed hair strands does not change quickly, the newly grown hair strands are still gray. Its permanence can only ensure the persistence of the color tone of the dyed hair strands, and most of them use aniline-based dye intermediates, whose irritation and toxicity are relatively high among cosmetic raw materials. Therefore, there is an urgent need for a product on the current market that is specifically targeted at blackening gray hair, especially the gray hair on both temples. Summary of the Invention

[0061] Typical Case 1
[0062] Verification of the effect of the composition of Example 1 on the blackening of gray hair on both temples
[0063] Ms. Wu, 53 years old. Before using the composition of the present invention, the gray hair on Ms. Wu's head was widely distributed, especially concentrated in the areas on both temples. After statistics, the number of gray hairs accounted for about 80% of the total number of hairs. The color of the gray hairs was silver-white, forming a sharp contrast with the surrounding black hairs, which was very obvious visually and seriously affected the overall appearance. In natural light, the gray hairs reflected light significantly, making the whole hair look dry and dull. Ms. Wu started to have gray hairs at the age of 39. She accidentally found a few gray hairs on both temples at that time and didn't pay attention. By the age of 53, the gray hairs had developed to the above-mentioned relatively serious degree, and the cumulative time of gray hair generation was about 14 years. During this period, Ms. Wu tried a variety of products on the market that claimed to have the effect of turning gray hair black, but none of them achieved obvious results.
[0064] Treatment method: After cleaning the hair and massaging the scalp, apply 10 mL of the composition of Example 1 once a day to the gray hair area until the scalp and hair roots, comb the hair for 10 minutes each time, and use the composition of Example 1 once every two days for a total of 60 days.
[0065] Calculate the blackening rate of gray hair (%) = (1 - the number of gray hairs after using the composition of the present invention ÷ the number of gray hairs before using the composition of the present invention) × 100%.
[0066] After 40 days of using the composition of Example 1, the gray hair on both temples of Ms. Wu began to significantly decrease, and the roots and hair of the gray hair on both temples turned black. After 60 days of using the composition of Example 1, the rate of turning gray hair black reached 80%.
[0067] After continuously using the composition of Example 1 for 60 days, the effects before and after are shown in Figure 1 。
[0068] Figure 1 The results show that most of the roots and hair of the gray hair on both temples of Ms. Wu have turned black, indicating that the composition of the present invention can significantly promote the turning of gray hair on both temples black.
[0069] Typical Case 2
[0070] Verification of the effect of the composition of Example 1 on turning gray hair on both temples black
[0071] Mr. Gao, 62 years old. Before using the composition of the present invention, his gray hair was mainly concentrated on both sides. The number of gray hairs accounted for about 80% of the total hair volume. Some of the gray hairs showed grayish-white color, mainly located on the gray hair on both temples. Since the gray hair was distributed in a prominent position on the forehead, it had a greater impact on the beauty of his face, making him look older than his actual age. Under indoor lighting, the gray hair was clearly visible. When he was 45 years old, there were some changes in his physical condition. At first, there were only dozens of gray hairs, and later, with the increase in work pressure and irregular living schedules, the number of gray hairs increased rapidly. By the age of 62, the gray hairs had been growing for 17 years. During these 17 years, Mr. Gao had suffered great psychological pressure due to his gray hair problem and lacked confidence in his aging image.
[0072] Treatment method: After cleaning the hair and massaging the scalp, apply 10 mL of the composition of Example 1 to the area with gray hair once a day to the scalp and hair roots, and comb the hair for 10 minutes each time. Use the composition of Example 1 once every other day for a total of 60 days.
[0073] Calculate the rate of turning gray hair black (%) = (1 - the number of gray hair roots after using the composition of the present invention ÷ the number of gray hair roots before using the composition of the present invention) × 100%.
[0074] After 30 days of using the composition of Example 1, the gray hair on both temples of Mr. Gao began to significantly decrease, and the roots and hair of the gray hair on both temples turned black. After 60 days of using the composition of Example 1, the rate of turning gray hair black reached 80%.
[0075] After continuously using the composition of Example 1 for 60 days, the effects before and after are shown in Figure 2 。
[0076] Figure 2The results show that the white hair roots and most of the hair on the temples of Mr. Gao have turned black, indicating that the composition of the present invention can significantly promote the blackening of white hair on the temples.
[0077] Typical Case 3
[0078] Verification of the effect of the composition of Example 1 on the blackening of white hair on the temples
[0079] Ms. Shen, 35 years old. Before using the composition of the present invention, the white hair on Ms. Shen's head was widely distributed, especially concentrated in the temple and top areas. After statistics, the number of white hair on the temples accounted for about 70% of the total hair. The color of the white hair was silver-white, and there was little black hair on the whole head. Visually, it looked very old and seriously affected the overall appearance. In natural light, the white hair reflected light significantly, making the whole hair look dry and dull. Duration of white hair generation: Ms. Shen stated that around the age of 30, due to multiple childbirths, her body was severely damaged and did not fully recover later. Before the age of 35, she had been dyeing her hair. In the following years, the number of white hair gradually increased. By the age of 35, the white hair had developed to a slightly severe degree, and the cumulative duration of white hair generation was about 5 years. During this period, Ms. Shen tried a variety of products on the market that claimed to have the effect of turning white hair black, but none of them achieved obvious results.
[0080] Treatment method: After hair cleaning and scalp massage, apply 10 mL of the composition of Example 1 to the white hair area once a day to the scalp and hair roots, comb the hair for 10 minutes each time, and use the composition of Example 1 once every other day for a total of 30 days.
[0081] Calculate the blackening rate of white hair (%) = (1 - the number of white hair roots after using the composition of the present invention ÷ the number of white hair roots before using the composition of the present invention) × 100%.
[0082] After using the composition of Example 1 for 30 days, the white hair on Ms. Shen's temples significantly decreased, the white hair roots and hair on the temples turned black, and after using the composition of Example 1 for 30 days, the blackening rate of white hair reached 90%.

Before using the composition of the present invention, there was extensive white hair distribution in Mr. Chen's hair, especially concentrated in the temples and the top of the head area. After statistics, the number of white hairs in the temples accounted for about 40% of the total number of hairs. The white hairs were silver-white in color, and there were relatively few black hairs on the whole head, which affected the overall appearance. In natural light, the white hairs reflected light significantly, making the whole hair look dull. Duration of white hair appearance: Mr. Chen stated that around the age of 35, due to excessive work pressure, often staying up late and having insomnia, he later had physical abnormalities. At the age of 35, he didn't care about having white hair. In the following years, the number of white hairs gradually increased. By the age of 43, there were already a certain number of white hairs, and the cumulative duration of white hair appearance was about 8 years. During this period, Mr. Chen tried a variety of products on the market that claimed to have the effect of turning white hair black, but none of them achieved obvious results.
[0088] Treatment method: After hair cleaning and scalp massage, 10 mL of the composition of Example 1 was applied once a day to the white hair areas until the scalp and hair roots, and the hair was combed for 10 minutes each time. The composition of Example 1 was used once every other day for a total of 30 days.
[0089] Calculate the blackening rate of white hair (%) = (1 - the number of white hair roots after using the composition of the present invention ÷ the number of white hair roots before using the composition of the present invention) × 100%.
[0090] After using the composition of Example 1 for 30 days, the white hairs in Mr. Chen's temples significantly decreased, and the hair roots and hair of the white hairs in the temples turned black.
