Black soybean (BS) is widely thought to prevent or alleviate hair loss, which has been demonstrated by in vitro experiments. However, few clinical studies have directly assessed the effect of BS on hair growth. To assess the safety and efficacy of BS, we administered BS extract to 10 adult patients for 3 months without any other hair products and treatments. The number and diameter of hair lost from washing were examined every 4 weeks. In addition, the participants' satisfaction with their hair condition was also measured using the VAS (1 to 10) before and after treatment. The mean number of lost hair was 140.7 (SD 59.4) at baseline and 38.8 (SD 54.4) after 12 weeks, and the diameter of lost hair was 72.4 ㎛ (SD 11.9) at baseline and 80.4 ㎛ (SD 8.8) after 12 weeks, which indicated a statistically significant improvement (p = 0.002, p = 0.022, paired t-test). The satisfaction score was significantly increased from 6.10 (SD 1.2) to 8.2 (SD 1.1) after 12 weeks. These results suggest that BS extract may promote hair growth and prevent hair loss.

Objective : As more and more people are interested in appearance in modern society, the increasing number of hair loss population can have an important impact on psychological and social problems such as depression and inappropriate interpersonal symptoms. Therefore, much research is being done on treatments for alopecia using herbal extracts with relatively few side effects. This study was investigated about the effect of Achyranthis Radix (AR) extract with ethanol solvent on hair growth. Methods : We determined the promoting efficacy of AR-ethanol extract compared with minoxidil (MNXD) on the growth of human hair dermal papilla cells (HDPCs). Cell viability was measured by MTT assay and cell proliferation was confirmed by cell cycle analysis from flow cytometry in HDPCs. Also, we monitored the safe concentration range through MTT assay. And protein expression of hair growth-related genes (insulin-like growth factor 1 (IGF-1), Wnt3a, Protein kinase B (Akt), Extracellular signal-regulated kinase (Erk)) was monitored by western blot. Results : On cell cycle analysis, the G2/M phase was higher than that of the DW group in AR ethanol extract group at 0.05 and 0.1 mg/㎖. All protein expression levels of HDPCs were increased in AR ethanol extract groups and the MNXD group, compared to the DW group, respectively. Conclusion : As mentioned above, AR extract increased cell proliferation and the protein expression of IGF-1, Wnt3a, Akt, Erk in HDPCs. These results suggest that AR ethanol extract has promoted hair growth and it might be potential hair growth supplement.

The hair growth effect of the oriental medicine extract which is composed of Polygoni multiflori Radix, Angelica gigantis Radix and Lycii Fructus was studied biochemically and histologically. The study was conducted dividelly into three groups, control, propecia and oriental medicine extract and three groups were compared each other in skin androgen, testosterone (T) and dihydrotestosterone (DHT), content biochemically and the number of hair follicular unit and hair follicle histologically. The oriental medicine extract and propecia decreased skin DHT conetent and increased skin total (T+DHT) content compared with control. In transverse sections of skin specimens the oriental medicine extract and propecia increased total counts of follicular units and follicles compared with control. On the basis of the result, the oriental medicine extract has same hair growth effect as propecia and it is suggested that the oriental medicne extract is capable of a therapeutic agent of alopecia.

The hair cycle consists of three phases, growth (anagen), involution (catagen) and quiescence (telogen) phases. In order to evaluate hair re-growth effect of herbal extracts mixture containing the 70％ ethanol extracts of Polygoni Multiflori Radix, Mori Cortex Radicis, Gingko Biloba Folium and Pine bud, we have examined the induction of the anagen phase and/or elongation of the anagen period using C3H mice. Morphological examination was done by Hattori' and Ogawa's method. Enzyme activities of ${\gamma}$-glutamyl transpeptidase (${\gamma}$-GT) and alkaline phosphatase (ALP) was detected by Bessey-Lovry-Brock's method. Enzyme activity as a biochemical marker of hair cycle was investigated in the third hair cycle period of C3H mice after depilation. 3％ Minoxidil treated group and herbal extract mixture treated group were shown 3 days earlier initiation of anagen than control group. In cycling mouse skin, ${\gamma}$-GT activity is pronounced during anagen and greatly diminished during telogen. Herbal extract mixture has shown promising hair re-growth effect on hair follicular cycles of C3H mice.

Hair loss affects both men and women of all ages and often significantly affects social and psychologic health. Recent therapeutic approach for hair loss such as finasteride and minoxidil focused on regulation of hormonal system blood flow. However, long-term use of these drugs caused adverse effects. To develop herbal medicine for therapeutic effect on hair growth, here we screened the 10 medicinal herbs (Red ginseng, Licorice, Ulmus, Barberry root, Lycium root, Rehmanniae radix crudus, Sophora root, Sweet flag, Polygala root, Achyranthes) based on oriental medicine literature. We measured cytotoxicity, anti-oxidant activity, and $5-{\alpha}$ reductase inhibitory effect of the herbal medicine on human dermal papilla (DP) cells to investigate therapeutic effect of the herbal medicine. Treatment of the 1% herbal medicine did not show any cytotoxic effects, and cell growth was increased by treatment of the 0.1% herbal medicine. In addition, the herbal medicine showed stronger antioxidant activity than resveratrol and comparable inhibitory activity of $5-{\alpha}$ reductase with finasteride. Furthermore, when applied to in vivo mouse model, we also observed increases in the number and length of hair of the herbal medicine-treated group. These results suggest that the herbal medicine promotes hair growth by its antioxidant activity and inhibitory activity of $5-{\alpha}$ reductase and might therefore be a promising hair growth-promoting agent.

Objectives : Mangifera indica leaves are well known for having a variety of benefits, including anti-inflammatory, anti-tumor, diabetic retinopathy and diabetic vasculosis. However, the effects of Mangifera indica leaves on hair loss inhibition have not been studied. In this study, we investigated to find out the activity of Mangifera indica leaves on hair loss. Methods : 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid(ABTS) analysis was performed to confirm the antioxidant efficacy of the water extract of Mangifera indica leaves (WEML). To examine the effect of WEML on cell viability in dermal papillar (DP) cells, 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetra Zolium (MTS) analysis was performed. The changes in the mRNA expression level of the hair loss and hair growth-related genes in dermal papilla cells by WEML treatment were confirmed by quantitative RT-PCR. Results : In dermal papilla (DP) cells, ABTS analysis and MTS analysis of WEML showed antioxidant efficacy and low cytotoxicity. As a result of gene expression analysis through Quantitative RT-PCR, no changes in hair growth-related genes BMP6 and CTNNB1 was confirmed. but inhibitory activity of WEML on hair loss-related genes EGR1, SGK, DKK1, SRD5A1 and SRD5A2 was confirmed. Conclusion : We confirmed that WEML has excellent antioxidant efficacy and a inhibitory activity of hair loss-related genes including 5α-reductase genes. These results suggest that Mangifera indica leaves have a potential activity as a hair loss treatment for hair loss and hair growth. Biochemical or molecular biological research on hair loss is needed.

Udenafil, which is a $PDE_5$ inhibitor, is used to treat erectile dysfunction. However, it is unclear whether udenafil induces hair growth via the stimulation of adipose-derived stem cells (ASCs). In this study, we investigated whether udenafil stimulates ASCs and whether increased growth factor secretion from ASCs to facilitate hair growth. We found that subcutaneous injection of udenafiltreated ASCs accelerated telogen-to-anagen transition in vivo. We also observed that udenafil induced proliferation, migration and tube formation of ASCs. It also increased the secretion of growth factors from ASCs, such as interleukin-4 (IL-4) and IL12B, and the phosphorylation of ERK1/2 and $NF{\kappa}B$. Furthermore, concomitant upregulation of IL-4 and IL12B mRNA levels was attenuated by ERK inhibitor or $NF{\kappa}B$ knockdown. Application of IL-4 or IL12B enhanced anagen induction in mice and increased hair follicle length in organ culture. The results indicated that udenafil stimulates ASC motility and increases paracrine growth factor, including cytokine signaling. Udenafil-stimulated secretion of cytokine from ASCs may promote hair growth via the ERK and $NF{\kappa}B$ pathways. Therefore, udenafil can be used as an ASC-preconditioning agent for hair growth.

In order to examine the clinical effects on male pattern hair loss, the oriental medicine extract composed of Polygoni multiflori Radix, Angelica gigantis Radix and Lycii Fructus was tested to balding people. 40 males and 10 females were participated in this experiment, and they had spread the extract on their scalp themselves one time a day for 18 months. After 18 months, all participants submitted the reports that had questionnaires to determine the effect of topical oriental medicine extract on hair growth and/or hair loss preventing in balding people. In the results, ir was found that hair density on the entire scalp was gradually increased during the spreading period of the extract in most of balding people. The hair loss was observed about 1 week or 2 months after extract treatment and hair growth was observed about 6 months after extract treatment. In the reports, 74％ of participants answered that the extract was effective on hair growth and hair loss preventing, and improvement of scalp condition. From these results, it is suggested that the extract composed of Polygoni multiflori Radix, Angelica gigantis Radix and Lycii Fructus may be an effective medical care to hair growth and hair loss preventing in human.
