Description

Technical Field

[0001] This invention relates to the field of shampoo technology, and in particular to a traditional Chinese medicine shampoo for treating oily hair loss and its preparation method. Background Technology

[0002] With the fast pace of life, increased work pressure, and environmental factors, the number of people suffering from oily hair loss is increasing. In traditional Chinese medicine, oily hair loss is often related to factors such as internal damp-heat, poor blood circulation, and liver and kidney deficiency. It manifests as excessive sebum secretion on the scalp, resulting in greasy, thinning, and falling hair, which seriously affects personal image and mental health.

[0003] Treatment options for oily hair loss mainly include chemical drug therapy, hair transplant surgery, and regular shampoo care. Chemical drug therapy primarily uses medications such as minoxidil and finasteride. While these can improve hair loss symptoms to some extent, long-term use may cause adverse reactions such as scalp irritation, itching, and redness, and in severe cases, may even affect physical health and quality of life. Hair transplant surgery is an invasive procedure with high costs and risks such as postoperative infection and low hair follicle survival rates, making it difficult for many patients to accept. Most regular shampoos on the market primarily function to cleanse the scalp and temporarily control sebum secretion. Their ingredients are mostly chemically synthesized surfactants and oil-controlling agents. Although they can temporarily alleviate scalp oiliness, they cannot fundamentally regulate the scalp environment and internal physiological functions, thus having limited effectiveness in treating oily hair loss. Long-term use may also cause chemical damage to the scalp and hair, further aggravating hair loss.

[0004] Currently, there are relatively few shampoos on the market that use traditional Chinese medicine as the main ingredient to treat oily hair loss. Moreover, the formulas of most products are not scientifically sound and have poor stability, resulting in insignificant treatment effects and failing to meet the needs of the majority of oily hair loss patients. Summary of the Invention

[0005] In view of this, the present invention proposes a traditional Chinese medicine shampoo for treating oily hair loss and its preparation method. The shampoo of the present invention can effectively regulate scalp sebum secretion, improve the scalp environment, promote hair growth, and has a good therapeutic effect on oily hair loss, with no obvious side effects, making it suitable for long-term use.

[0042] 2. Therapeutic effect of treatment on oily hair loss in mice Sixty-six six-week-old male C57BL / 6J mice, weighing 20-25g, were acclimatized for seven days in an environment of 20-24℃, 55±5% relative humidity, and 12h light / 12h darkness. The mice were then anesthetized, and hair was removed from the same area on the back of the mice using hair removal cream. The area to be hair removed was 2cm×3cm. The mice were then divided into a normal group and a model group, with 6 mice in the normal group and 60 mice in the model group. Oily hair loss was induced in mice by injecting testosterone propionate (solvent: olive oil) at a dose of 5 mg / kg into their backs once daily for 21 consecutive days. On day 21, the mice's skin was observed to be noticeably oily, and their hair was sparse and prone to falling out. Compared with the normal group, the hair loss area on the backs of the model group mice reached (2.5±0.3) cm², confirming successful modeling. The successfully modeled mice were randomly divided into 10 groups of 6 mice each, corresponding to the herbal shampoo groups of Examples 1-3 and Comparative Examples 1-6, and the positive control group, respectively. Mice in the herbal shampoo groups applied 5 mL of the herbal shampoo prepared in Examples 1-3 and Comparative Examples 1-6 evenly to the hair loss area daily, gently massaging for 5 minutes (focusing on areas with high sebum secretion), and rinsing thoroughly with 37°C warm water to ensure no drug residue. This was done 6 times a week. The normal group and the positive control group were treated with the same amount of physiological saline for 28 consecutive days.

[0043] After 28 days, five fixed sites were selected in the hair-removed area of ​​the mice. The number of hairs at each site was observed and counted using an optical microscope, and the average hair density was calculated. After 28 days, 10 hairs were randomly selected from each hair-removed area of ​​the mice, and the hair diameter was measured using an optical microscope, and the average value was taken. After 28 days, skin tissue from the hair-removed area of ​​the mice was removed, fixed, embedded, sectioned, and stained with hematoxylin and eosin (HE). The number of hair follicles was observed under an optical microscope, with five high-power fields observed for each sample, and the average number of hair follicles was calculated. 200 μL of blood was collected using the cardiac blood sampling method, and serum was separated by centrifugation at 3000 rpm for 10 minutes. The levels of vascular endothelial growth factor (VEGF) and TGF-β1 were measured using an ELISA kit. The results are shown in the table below.

[0044] Table 2. Effects of Traditional Chinese Medicine Shampoo on Oily Hair Loss Mouse Model

[0045] Compared with Comparative Examples 1-6, the herbal shampoos prepared in Examples 1-3 of this invention can further promote the increase of hair density. Furthermore, the hair diameter in the example groups is superior to that in the comparative examples, and the average number of hair follicles in the example groups is also greater than that in the comparative examples. These results indicate that the herbal shampoo of this invention, through the synergistic effect of raw materials such as *Prunella vulgaris*, *Verbena officinalis*, *Equisetum hyemale*, *Usnea indica*, *Ligusticum striatum*, and *Arctium lappa*, can help the active ingredients penetrate the skin, exhibiting good transdermal absorption. It effectively inhibits scalp sebum secretion, thereby promoting blood circulation in hair follicles, promoting hair follicle cell proliferation, and promoting hair growth. In addition, compared with the comparative example, the herbal shampoo of the present invention can increase the VEGF content and decrease the TGF-β1 content after action, indicating that the herbal shampoo of the present invention can regulate hair growth factors VEGF and TGF-β1, reduce the occurrence of inflammation, promote cell growth and the formation of microvessels in the scalp, promote hair growth and promote the proliferation of hair follicle cells, thereby playing a good role in treating oily hair loss.
