[0017] One embodiment of the present invention provides a natural extract for promoting black hair and black hair, comprising the following components in percentage by mass: 32-38% of Polygonum multiflorum extract, 18-22% of Platycladus orientalis leaf extract, 18-22% of mulberry fruit extract, 10-15% of Cornus officinalis extract, and 10-15% of Ligusticum chuanxiong extract; the Polygonum multiflorum extract is an extract obtained by reflux extraction of Polygonum multiflorum with an ethanol aqueous solution having a volume percentage of 55-65% at 65-75°C for 1-1.5h; the Platycladus orientalis leaf extract is an extract obtained by reflux extraction of Platycladus orientalis leaf with an ethanol aqueous solution having a volume percentage of 72-78% at 68 The extract is obtained by reflux extraction at -72°C for 1.2-1.5 hours; the mulberry fruit extract is obtained by ultrasonically extracting mulberry fruit with a 0.1% by volume hydrochloric acid ethanol solution at 43-48°C for 20-30 minutes; the cornus officinalis extract is obtained by reflux extraction of cornus officinalis with a 48-52% by volume ethanol aqueous solution at 78-83°C for 2-2.5 hours; and the Chuanxiong rhizome extract is a mixture of an extract obtained by steam distillation of Chuanxiong rhizome for 4-5 hours and an extract obtained by ultrasonically extracting Chuanxiong rhizome in an ethanol solution at 58-65°C for 20-30 minutes. Among the above natural extracts, Polygonum multiflorum extract, Platycladus orientalis leaf extract, mulberry fruit extract, Cornus officinalis extract, and Chuanxiong rhizome extract are scientifically formulated, resulting in significant synergistic effects between the components, which can effectively promote the activity of hair follicle cells and increase the synthesis of melanin, thereby achieving excellent black hair and dark hair effects.
[0018] Components such as emodin and chrysophanol in the Polygonum multiflorum extract obtained by the above method can promote the production and activity of melanocytes, providing a foundation for black and dark hair. Components such as flavonoids in the Platycladus orientalis leaf extract obtained by the above method can improve scalp blood circulation, provide sufficient nutrition to hair follicles, and contribute to melanin synthesis and hair growth. Components such as vitamins, minerals, and anthocyanins in the mulberry fruit extract obtained by the above method can nourish hair and promote melanin synthesis. They synergize with the Polygonum multiflorum extract to enhance the blackening effect of hair. The Cornus officinalis extract obtained by the above method can provide a good environment for hair growth and work in conjunction with other components to improve hair condition. The Chuanxiong Rhizome extract obtained by the above method can promote scalp blood circulation and enhance the nutrient supply to hair follicles. It synergizes with the Platycladus orientalis leaf extract to further improve nutrient supply efficiency. It also works in conjunction with other components to promote melanin synthesis and healthy hair growth.
[0019] It is understood that in the above-mentioned preparation methods of natural extracts, the 55-65% by volume ethanol-water solution represents a solution composed of ethanol and water, wherein the volume percentage of ethanol is 55-65%. The 72-78% by volume ethanol-water solution represents a solution composed of ethanol and water, wherein the volume percentage of ethanol is 72-78%. The 0.1% by volume hydrochloric acid-ethanol solution represents a solution composed of hydrochloric acid and ethanol, wherein the volume percentage of hydrochloric acid is 0.1%. The 48-52% by volume ethanol-water solution represents a solution composed of ethanol and water, wherein the volume percentage of ethanol is 48-52%.

Within this mass ratio range, the volatile oils and other active ingredients of the two extracts work synergistically to promote blood circulation in the scalp, enhance nutrient supply to hair follicles, and further enhance the effect of darkening and blackening hair in collaboration with other components. The two extraction methods complement each other and can fully extract the active ingredients in Chuanxiong. Alternatively, the mass ratio of the two extracts can be 5:1, 6:1, 7:1, 8:1, etc.

Furthermore, the natural extract for promoting black hair and dark hair comprises the following components in percentage by weight: 35% Polygonum multiflorum extract, 20% Platycladus orientalis leaf extract, 20% Morus alba extract, 12% Cornus officinalis extract, and 13% Ligusticum chuanxiong extract.
[0022] Another embodiment of the present invention provides a method for preparing the aforementioned natural extract for promoting dark hair or black hair, comprising the steps of: weighing the extracts according to mass percentages and mixing them uniformly to obtain the natural extract for promoting dark hair or black hair. This method is simple and easy to implement, and is suitable for industrial promotion.
[0023] Another embodiment of the present invention provides an application of the above-mentioned natural extract having the effect of promoting black hair and dark hair in hair care products.
[0024] Optionally, the above application includes the following steps: mixing the natural extract that promotes black hair and dark hair with auxiliary materials.
[0025] It is understandable that the auxiliary materials can be conventional auxiliary materials in hair care products, which will not be described in detail here.
[0026] Another embodiment of the present invention provides a hair care product, comprising the above-mentioned natural extract having the effect of promoting black hair and dark hair.
[0027] Optionally, the natural extract that promotes black hair or black hair efficacy accounts for 3%-10% of the mass percentage of the hair care product. For example, the natural extract that promotes black hair or black hair efficacy accounts for 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10% of the mass percentage of the hair care product.

[0046] Test Case
[0047] 140 volunteers aged 18-30 with premature graying of hair were selected (70 males and 70 females). They were randomly divided into seven groups, each consisting of 20 participants, with an equal number of males and females. Each group was treated with a shampoo made with the natural extracts from the corresponding Examples or Comparative Examples (the natural extracts comprised 3% of the shampoo by weight) once every three days for two consecutive months.
[0048] (1) White Hair Blackening Rate: Observe and record the percentage of white hair that has turned black compared to the original number of white hairs in each group of volunteers after 2 months of use. The average value of each group is used as the revised test value. The results are shown in Table 1.
[0049] (2) Increase in Hair Melanin: A melanin detector was used to measure the melanin content in the hair of each group of volunteers before and after two months of use. The increase in melanin was calculated as follows: Melanin Increase = (Melanin Content After Use - Melanin Content Before Use) / Melanin Content Before Use × 100%. The average value for each group was used as the revised test value. The results are shown in Table 1.
[0050] Table 1
[0051] White hair turning black rate Increased hair melanin Example 1 76.3％ 55.6％ Example 2 72.5％ 50.9％ Example 3 68.7％ 47.3％ Comparative Example 1 49.2％ 32.4％ Comparative Example 2 35.7％ 20.5％ Comparative Example 3 46.8％ 29.8％ Comparative Example 4 43.3％ 26.4％
[0052] It can be seen from Table 1 that the black hair effect of the natural extracts in the examples is significantly better than that in the comparative examples, and it can be seen from Example 1 and Comparative Example 2 that different preparation methods of the extracts have an important influence on the black hair effect of the natural extracts.
[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
