Abstract
Description
Technical Field
[0001] The present invention relates to the field of cosmetics, and particularly to a hair-fixing and anti-hair loss composition, its application, and a hair-fixing and anti-hair loss product. Background Art
[0002] The problem of hair loss is multi-dimensional, and its impact is not limited to the appearance level, but more widely involves multiple aspects such as mental health, social activities, economic status, and medical health. From a psychological perspective, hair loss can significantly reduce an individual's self-esteem and self-image perception, thereby inducing negative psychological states such as anxiety and depression, having an adverse impact on social activities, and in severe cases, may even lead to social isolation. At the same time, gender identity and personal attractiveness may also be impacted by hair loss. In the field of sociology, the negative impact of hair loss on career development cannot be ignored, especially in those professional fields with strict appearance requirements, where the impact is more significant. In addition, hair loss may also interfere with the evaluation of self-confidence and attractiveness in interpersonal relationships, reducing the overall quality of life. Economically, the financial burden brought by hair loss treatment cannot be ignored, including the high costs of hair transplantation and special hair care products.
[0003] Hair loss is a complex physiological phenomenon affected by multiple factors. There are many reasons for hair loss. External environments such as ultraviolet rays, chemical substances, and heat treatment can all damage the hair and exacerbate hair loss. Research shows that nutritional status is also crucial for hair health. Lack of nutrients such as protein, iron, zinc, and vitamins will directly affect hair growth and quality. At the same time, certain systemic diseases, such as thyroid diseases and autoimmune diseases, are also closely related to hair loss. Drug use is also a major inducement of hair loss. Many drugs such as chemotherapy drugs and antidepressants may cause hair loss. Scalp health problems cannot be underestimated either. Microbiological imbalance, fungal infection, and inflammatory diseases can all lead to hair loss. Psychological factors such as stress and anxiety indirectly affect hair growth by influencing hormone levels and the immune system. Physical damage, poor hair care habits, and physiological processes such as pregnancy and childbirth may also cause hair loss. Finally, as people age, the hair growth cycle changes, which is also an important reason for hair loss.
[0004] Genetic factors are also key factors affecting hair loss. Especially in androgenetic alopecia, genetic susceptibility plays a decisive role. Changes in hormone levels cannot be ignored either. For example, an increase in androgens can trigger follicular atrophy, thereby leading to hair loss. Hair follicle stem cells play a key role in the hair growth cycle. The hair growth cycle includes the anagen, catagen, and telogen phases. Among them, hair follicle stem cells are activated during the anagen phase to promote the growth of new hair. The decline or disorder of the function of hair follicle stem cells can cause hair loss because they cannot maintain the anagen phase of the hair follicle, resulting in sparse and falling hair. Especially in androgenetic alopecia, androgens may interfere with hair follicle stem cells, triggering follicular atrophy and hair thinning.
[0005] At present, there are also a large number of anti-hair loss compositions and formulations on the market. Chinese Patent Application CN118845516A discloses an anti-hair loss composition, which is composed of adenosine, coffee extract, L-carnitine tartrate, tripeptide-1 copper, Platycladus orientalis extract and niacinamide. This composition has a significant synergistic effect in improving cell antioxidant capacity and inhibiting 5α-reductase. However, this composition has no obvious effect on inhibiting the senescence or disorder of hair follicle stem cells and maintaining the growth phase of hair follicles. Summary of the Invention

[0141] (2) Administration and stimulation. Administration and stimulation were carried out according to the test grouping, and administration and stimulation were carried out simultaneously. Each group was set with 3 duplicate wells. The BC (blank control) group added 2 mL of culture medium to each well, the NC (negative control) group added 2 mL of culture medium containing H 2 O 2 to each well, the PC (positive control) group added 2 mL of culture medium containing H 2 O 2 and WY14643 to each well, and the sample group added culture medium containing H 2 O 2 and the test sample at the corresponding concentration to each well. After completion, all 6-well plates were transferred to a CO 2 incubator (37 °C, 5% CO 2 ) for incubation for 24 hours.
[0142] (3) After the incubation was completed, the old liquid was aspirated and discarded, washed twice with 1 mL / well of PBS, 1 mL of AG RNAex ProReagent was added to each well, the cells were lysed by pipetting, and the samples were collected. After extracting RNA and reverse transcribing it into cDNA, fluorescence quantitative PCR detection was carried out, and the 2 -△△CT method was used for calculation.
[0143] (4) Calculation of upregulation rate:
[0144]
[0145] For each sample, the average value of the test results of 3 duplicate wells was taken and recorded in Tables 3 - 5.
[0146] 2. Test results
[0147]
[0148] The experimental results are shown in Table 3 and Figure 3 as follows. After treatment with the above concentrations, the upregulation rate of the COL 17 gene expression was 44.23% for Component 1 (type 17 collagen), and 17.31% for Component 2 (extract of Platycladus orientalis leaves); after treatment with the above concentrations, the COL 17 gene expression increased slightly for Components 3 - 5, 7, 8, and 10 - 13, but the upregulation rate did not exceed 10%; after treatment with the above concentrations respectively for Components 6 and 9, the COL 17 gene expression did not increase.
[0149] After treatment with the above concentrations in Examples 1-7, the expression level of the COL 17 gene increased significantly, and the up-regulation rate ranged from 89.74% to 159.62%. Among them, Example 7 had the highest up-regulation rate of the COL 17 gene expression. Compared with Comparative Examples 1-5, Example 1 had a higher up-regulation rate of the COL 17 gene expression. It can be seen that, compared with other plant extracts, type 17 collagen and L-carnitine tartrate have a better cooperative effect with Platycladus orientalis leaf extract.
[0150]
[0151] As shown in Table 4 and Figure 4 as shown, after treatment with the above concentrations, the up-regulation rate of the TGF-β2 gene expression of Component 1 (type 17 collagen) was 144.81%, and the up-regulation rate of the TGF-β2 gene expression of Component 2 (Platycladus orientalis leaf extract) was 38.31%; after treatment with the above concentrations of Components 3-11 and 13, the TGF-β2 gene expression increased slightly, but the up-regulation rate did not exceed 20%; after treatment with the above concentrations of Component 12, the TGF-β2 gene expression did not increase, but decreased slightly.
[0152] After treatment with the above concentrations in Examples 1-7, the expression level of the TGF-β2 gene increased significantly, and the up-regulation rate ranged from 314.9% to 442.21%. Among them, Example 7 had the highest up-regulation rate of the TGF-β2 gene expression. Compared with Comparative Examples 1-5, Example 1 had a higher up-regulation rate of the TGF-β2 gene expression. It can be seen that, compared with other plant extracts, type 17 collagen and L-carnitine tartrate have a better cooperative effect with Platycladus orientalis leaf extract. An increase in TGF-β2 gene expression can promote the transformation of hair follicle stem cells from the quiescent phase to the growth phase, which is more beneficial for hair retention.
[0153]
[0154] As shown in Table 5 and Figure 5 as shown, after treatment with the above concentrations, the up-regulation rate of the VEGFA gene expression of Component 1 (type 17 collagen) was 128.16%, and the up-regulation rate of the VEGFA gene expression of Component 2 (Platycladus orientalis leaf extract) was 63.79%; after treatment with the above concentrations of Components 3-13, the VEGFA gene expression increased slightly, but the up-regulation rate did not exceed 23%.
[0155] After the treatments at the above concentrations in Examples 1 - 7, the expression level of the VEGFA gene increased significantly, with the up - regulation rate ranging from 184.48% to 239.66%. Among them, Example 7 had the highest up - regulation rate of the VEGFA gene expression level. Compared with Comparative Examples 1 - 5, Example 1 had a greater up - regulation rate of the VEGFA gene expression level. It can be seen that, compared with other plant extracts, type XVII collagen and L - carnitine tartrate have a better synergistic effect with Platycladus orientalis leaf extract.

The BC (blank control) group adds 2 mL of culture medium to each well, the NC (negative control) group adds 2 mL of culture medium containing H 2 O 2 , the PC (positive control) group adds 2 mL of culture medium containing H 2 O 2 and WY14643, and the sample group adds culture medium containing H 2 O 2 and the test sample at the corresponding concentration. After completion, transfer all 6 - well plates to a CO 2 incubator (37 °C, 5% CO 2 ) and incubate for 24 hours.
[0160] (3) Use a β - galactosidase staining kit to stain the cells after treatment with the test substances, and count the proportion of senescent cells among all cells.
[0161] For each sample, take the average of the test results of 3 replicate wells and record it in Table 6.
[0162] 2. Test results
[0163]
[0164] The experimental results are shown in Table 6 and Figure 6As shown, compared with Components 1-13, Examples 1-7 have significantly improved in inhibiting the senescence of dermal papilla cells; among all the compositions, the composition of Example 7 has the strongest ability to inhibit the senescence of dermal papilla cells. Compared with Comparative Examples 1-5, Example 1 has a stronger ability to inhibit the senescence of dermal papilla cells. It can be seen that compared with other plant extracts, type XVII collagen and Platycladus orientalis extract have a better cooperative effect.
[0165] Application Example 1: Preparation of Hair Care Essence
[0166] According to the formula in Table 7, use the anti-hair loss and hair strengthening composition of Example 7 to prepare the hair care essence. The preparation process is as follows:
[0167] Add raw material water and dipropylene glycol into the main pot respectively, stir evenly, then add type XVII collagen and stir until completely dissolved; first premix the plant extracts (Platycladus orientalis extract, Magnolia officinalis extract, Polygonum multiflorum extract, Zingiber officinale extract, Salvia miltiorrhiza extract and Coffea arabica extract) with a certain amount of water, after premixing evenly, add them into the main pot and stir evenly; then add adenosine, L-carnitine tartrate, myristoyl pentapeptide-4, acetyl tetrapeptide-3, tripeptide-1 copper and niacinamide, and stir evenly; then add dipotassium glycyrrhizinate and VE derivative, and stir evenly; test the pH of the material, and add arginine to adjust the pH to 6-7.
[0168]
[0169] The anti-hair loss and hair strengthening efficacy was tested through mouse experiments. Mice in the telogen phase (skin is pink) were selected for the experiment. Take 18 male SPF-grade C57BL / 6 mice, 6-7 weeks old. After 7 days of adaptive feeding of the mice, they were randomly divided into 3 groups according to body weight, namely the normal control group, the positive control group, and the test article group, with 6 mice in each group. Under the anesthesia of the mice, select an area of about 2 cm×3 cm on their backs as the depilation area, and the long side of this area is parallel to the spine. Use a hair clipper to shave the hair in this area, and further depilate with depilatory cream. After pre-hair removal, the mice in the test article group were treated with the test article (the hair care essence of Application Example 1) by skin application, and the intervention period was 21 days. The mice in the normal control group were smeared with normal saline, and the positive control group was smeared with a commercially available competitor (5% minoxidil). The specific grouping and administration information are shown in Table 8:
[0170]
[0171] The mice in each group were photographed every day before and after the intervention to record the skin and hair color of the depilation area. And the hair growth of the mice was scored on the 3rd, 7th, 10th, 14th, and 21st days before and after the intervention. The hair scoring criteria are shown in Table 9, and the scoring results are as Figure 7 shown.
[0172]
[0173] After the administration was completed, the hair quality and hair length of the newly grown hair in the depilated areas of the mice in each group were measured. After removing the newly grown hair in the depilated area, it was weighed, and the hair quality was recorded per square centimeter of skin. In addition, 50 hairs were randomly selected from each mouse, fixed with transparent tape, and the length of the newly grown hair in the depilated area was measured with a ruler, and the measurement results were recorded. The measurement results are shown in Table 10, Figure 8 and Figure 9 as shown
[0174]
[0175] The test results showed that compared with the normal control group and the positive control group, the mice using the hair care essence of the present invention had faster hair growth. By 14 days, more than 80% of the area had hair growth, and the hair was longer and heavier.
