Description

Technical Field

[0001] The invention relates to the technical field of plant fermentation extraction, in particular to a hair growth and blackening liquid and a preparation method thereof. Background Art

[0002] In modern society, with the accelerated pace of life, increased pressure and the influence of environmental factors, hair loss and gray hair problems are becoming increasingly common, causing trouble for many people. Hair loss not only affects personal image, but may also have a negative impact on the patient's psychological state and reduce the quality of life. The appearance of gray hair can also make people look older than their actual age, causing aging anxiety.

[0003] There are many kinds of hair growth and darkening products on the market, but most of them have certain limitations. Many traditional hair growth products mainly focus on stimulating hair follicles and promoting hair growth, but they are not effective in improving hair color and enhancing hair health. Although some darkening products can temporarily change hair color, they often contain a large amount of chemicals. Long-term use may cause damage to the scalp and hair, such as scalp allergies, dry and brittle hair, and other problems. Moreover, existing hair growth and darkening products lack the full use of natural and efficient ingredients in raw material selection and formula design. The synthetic ingredients used in some products cannot fundamentally solve key problems such as hair follicle nutrition supply and melanin production.

[0004] In terms of raw material extraction and preparation technology, traditional methods also have many shortcomings. For example, common plant essence extraction methods may not be able to fully extract the active ingredients, resulting in a significant reduction in product efficacy. At the same time, impurities may be introduced during the extraction process, affecting product quality and safety. For some precious raw materials, unreasonable extraction processes may also cause waste of resources.

[0005] The hair growth and darkening liquid of the present invention is born based on such a background. It uses a variety of natural plants such as desert black ginseng, cypress leaves, and Usma grass as raw materials. These plants are rich in a variety of ingredients that are beneficial to hair follicle health and melanin production. Through a unique formula design, the effects of each raw material are organically combined, which can not only promote hair growth, but also achieve the effect of darkening hair. In terms of preparation technology, advanced technology is used to ensure the full extraction and activity retention of effective ingredients, thereby improving the overall performance of the product, and providing a more scientific, safe and effective solution to the problem of hair loss and gray hair. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a hair growth and darkening liquid which can promote hair growth and achieve the effect of darkening hair and a preparation method thereof.

According to the detection of professional institutions, these raw materials do not contain substances harmful to the human body and meet the national safety standards for food and drug raw materials. For example, desert black ginseng is rich in various nutrients and has been recorded as a medicine and food in traditional medicine; after special pretreatment of Platycladus orientalis leaves, its active ingredients are not only beneficial to the scalp, but can also be used for internal conditioning under reasonable dosage control;

[0107] 2. Toxicity test: During the development of this product, a professional third-party testing agency was commissioned to conduct strict toxicity tests. The tests covered acute toxicity tests, long-term toxicity tests, skin irritation and allergy tests, etc. The results showed that no toxic reactions and obvious skin irritation or allergy occurred within the normal dosage range, whether it was taken orally or applied externally. This provides a strong scientific basis for the product to be taken orally or applied externally;

[0108] 3. Clinical trials: During the clinical trial phase of the product, a total of 300 volunteers were recruited, some of whom took the product orally, some took it externally, and some took it in combination. After three months of follow-up observation, the volunteers' physical reactions and hair growth and darkening effects were recorded in detail. The results showed that none of the three methods of use had any adverse effects on the volunteers' physical health, and all achieved certain effects in promoting hair growth and darkening, further verifying the feasibility of the product for both internal and external use.

[0109] The specific usage of the hair growth and darkening liquid of the present invention for oral administration is:

[0110] Take 5 ml of the hair growth liquid twice a day, dilute it with about 100 ml of warm water, and take it within half an hour after a meal. During the period of taking it, it is recommended to keep a light diet and avoid eating spicy, greasy and irritating foods.

[0111] The specific usage of the hair growth and darkening liquid of the present invention is as follows:

[0112] After washing and drying your hair, apply 3-5 ml of hair growth liquid evenly on the scalp, and gently massage the scalp with your fingertips for 5-10 minutes to allow the product to fully penetrate and absorb. The intensity of the massage should be moderate to avoid excessive force that can damage the scalp. The frequency of external application is once in the morning and once in the evening every day. There is no need to wash after use, and the product can be allowed to work naturally on the scalp.

[0113] Note:

[0114] Before using this product, it is recommended to conduct a skin allergy test behind the ear or on the inside of the arm and observe for 24 hours. If there is no allergic reaction, it can be used normally. If any discomfort symptoms occur during use, such as itchy scalp, redness, swelling, nausea, vomiting, etc., stop using it immediately. At the same time, this product should be placed out of reach of children to prevent them from accidentally taking it.

[0115] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
