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.

Grateloupia elliptica has been reported to have the proliferation effect of dermal papilla cells (DPCs), which play important roles in the regulation of hair cycle. In the present study, we examined in vitro and in vivo hair growth-promoting effect of Grateloupia elliptica. When isolated rat vibrissa follicles were treated with extract of G. elliptica, the hair-fiber lengths of the vibrissa follicles significantly increased. Furthermore, the G. elliptica extract accelerated the telogen-angen transition in C57BL/6 mice. To investigate the molecular mechanisms of the G. elliptica extract on the proliferation of DPCs, we examined the activation of $wnt/{\beta}$-catenin signaling which is known to regulate hair follicle development, differentiation and hair growth. The G. elliptica extract activated $wnt/{\beta}$-catenin signaling via the increase of ${\beta}$-catenin and phospho-$GSK3{\beta}$. In addition, the G. elliptica extract increased the level of cyclin E and CDK2, while the level of $p27^{kip1}$ was decreased. These results suggest that the the G. elliptica extract may induce hair growth by proliferation of DPCs via cell-cycle progression and the activation of $Wnt/{\beta}$-catenin signaling.

It is commonly believed that black soybean (Glycine max: BB) prevents and alleviates hair loss. However, few studies have directly assessed the effect of BB on hair growth. We presently evaluated the mitosis induction on dermal papillae cell and mitogenic effect on NIH3T3 cells in vitro. To elucidate the hair growth promoting effect in vivo, anagen induction and hair restoration were examined in a shaving model of C57BL/6 mice. We also conducted biochemical analysis of blood plasma. Significant stimulation of dermal papillae and NIH3T3 cell proliferation were observed by treatment of BB in a dose-dependent manner. BB markedly promoted hair growth and significantly improved blood total antioxidant capacity and reduced lipid peroxidation and triglyceride level. These results suggest that BB has hair growth promoting effect and it is a potent candidate for the prevention of hair loss.

In Korean folk medicine, several herbs, Glycyrrhizae Radix, Persicae Semen, Salviae Radix, Angelicae Gigantis Radix, Zanthoxyli Fructus, Ginseng Radix Alba, Cnidii Rhizoma, and Carthami Flos, are known to enhance blood circulation and have wound healing or anti-inflammatory effects. These pharmacological actions prompted us to investigate whether these herbs might stimulate hair growth. Thus, using a mixture of their extracts called SPELA 707, we investigated their effects and found that SPELA 707 possessed significant hair cycle converting activity from the telogen phase to the anagen phase in C3H mice. Furthermore, we found that SPELA 707 enhanced the hair density in subjects with hair loss and also promoted the conversion of hair into the anagen phase in subjects with androgenetic alopecia. In addition, hair growth promotion effect of SPELA 707 occurred through inhibition of steroid $5{\alpha}$-reductase activity, which is known to block hair growth. Taken together, these results suggest that SPELA 707 has a potential to be used for the treatment of hair loss.

Objectives: Yonnyuniksoogobon-dan (Yan Nian Yi Shou Gu Ben Dan 延年益壽固本丹) is composed of 11 herbs (Polygoni Mutiflori Radix, Lycii Radicis Cortex, Polia, Rehmanniae Radix, Rehmanniae Radix Preparat, Asparagi Radix, Liriopis Tuber, Lycii Fructus, Acori Graminei Rhizoma, Angelicae Acutiloba Radix, and Pini Folium) based on Yonryunggobon-dan (Yan Ling Gu Ben Dan 延齡固本丹) and Yonnyuniksoobulrho-dan (Yan Nian Yi Shou Bu Lao Dan 延年益壽不老丹). This study evaluated hair growth promoting effect of Yonnyuniksoogobon-dan on the shaved C57BL/6 mice. Methods: Yonnyuniksoogobon-dan was treated by oral administration (Sample I) and oral administration plus skin application (Sample II) once a day for 12 days. Hair regrowth was photographically and histologically determined during the experimental period. Hair growth cycle related factors (EGF, TGF-${\beta}1$) and vascular factors (VEGF, iNOS) were also determined with immunohistochemistry. Results: 1. On gross observation of hair regrowth, Sample I and Sample II groups demonstrated acceleration of hair regrowth. 2. The hair regrowth index of the Sample I group increased significantly from 7 days (P<0.05) to 12 days (P<0.01) after the shave while that of the Sample II group significantly increased at 12 days (P<0.05). 3. On histological observation, both Sample I and Sample II groups demonstrated histological improvement and increases of number and diameter of the hair follicles. 4. EGF expressions on the root sheath of hair follicles were up-regulated in both Sample I and Sample II groups. 5. TGF-${\beta}1$ expressions on the root sheath of hair follicles were not regulated in Sample I or Sample II groups. 6. VEGF expressions in the surrounding tissues of hair follicles were up-regulated in both Sample I and Sample II groups. 7. iNOS expressions in the surrounding tissues of hair follicles were down-regulated in both Sample I and Sample II groups. Conclusions: These results suggest that Yonnyuniksoogobon-dan has hair growth-promoting activity and these effects relate to up-regulations of EGF and VEFG expressions and down-regulations of TGF-${\beta}1$ and iNOS expressions on hair roots.

Recently, increased attention has been directed toward medicinal extracts and their active ingredients as potential new drug candidates for androgenic alopecia. Resina Pini (RP), a resinous exudation obtained from Pinus sp. (Pinaceae), has been used as a traditional medicine for the treatment of infection, pain related to dental caries, and periodontal disease. Previously, we suggested that RP and its main constituent, abietic acid (abieta-7,13-dien-18-oic acid; AA), may play important roles against androgenic alopecia as $5{\alpha}$-reductase inhibitors. However, to date, there is no evidence that AA has hair growth-promoting effects in vivo. In this study, we found that 10 ~ 300 mg/kg RP and 3 ~ 30 mg/kg AA significantly promoted hair growth in a C3H/HeN mouse model of alopecia. To our knowledge, this is the first report of the hair growth-promoting effects of RP and AA in vivo. From these results, RP and its main constituent AA can promote hair growth in mouse by inhibiting $5{\alpha}$-reductase activity and may be effective alternative therapies for androgenic alopecia.

Thuja orientalis extract (TOS) has been used on the hemostatic roborant, sedatives and stressless in oriental countries. We investigate the inhibitory effects on the productions of pro-inflammatory cytokines such as interleukin-1beta (IL-1β), IL-6, tumour necrosis factor alpha (TNF-α), and nitric oxide (NO) and the hair promotiont of TOS in the macrophage celline RAW264.7 or hair loss-induced DBA1J mice. T08 (50-500 ㎍/㎖) per se had no cytotoxic effect non-stimulated cells, but this extracts concentration-dependently reduced the release of NO, (IL-1β), IL-6, and TNF-α in the stimulate RAW264.7 cells with lipopolysaccharide (LPS). Moreover, when applied TOS (500 ㎍/㎖) to DBA 1J/mice, hair growth was promoted remarkably. These data suggest that T08 promotes hair growth on hair loss induced model mice and these properties may contribute to the anti- hair loss activity of the Thuja orientalis.

The bacterial growth and pH of Cornus officinalis fermented with Lactobacillus rhamnosus during fermentation were evaluated. As the results, the number of the fermentation after fermentation always remained higher than 6 log CFU/mL and the pH of those ranged from 4 to 6. To evaluate the effect of Cornus officinalis fermented with Lactobacillus rhamnosus on hair growth promotion in C57BL/6 mice, Six weeks old male mice were divided into four groups including normal group (saline), negative control group (essence base), positive control group (minoxidil) and experimental group (Cornus officinalis and animal milk fermented with Lactobacillus rhamnosus mixed in negative control). And they were applied topically with test materials for 8 days. Hair regrowth effect in experimental group using gross and histological examination was higher than that in positive control group. Body weight and food intake of four groups didn't show significant difference. These results indicated that the Cornus officinalis fermented with Lactobacillus rhamnosus can be used practically for hair growth or prevention of hair loss.

Emodin is an anthraquinone derivative from the roots of Rheum officinale Baill that possesses a variety of biological activities, including inhibition of $5{\alpha}$-reductase and prostaglandin D2. In this study, we investigated whether emodin promotes hair growth. After emodin was topically applied to the shaved dorsal skin of telogenic C57BL/6 N mice, the hair growth rate and morphological analysis were evaluated in dorsal skin for 15 days. After 13 days of treatment, minoxidil or emodin (0.01% or 0.1%)-treated groups showed remarkable regrowth of hairs relative to the vehicle control group. Scoring of the hair growth and rate of hair growth area for 15 days revealed that groups treated with minoxidil and 0.1% emodin were significantly higher than the vehicle control group. Histological examination revealed the emodin and minoxidil groups markedly recovered the number and morphology of hair follicles, including the subcutis depth, relative to the vehicle group. These results suggest that emodin has an excellent promoting effect in hair growth similar to that of minoxidil and might be useful for treatment of baldness or alopecia.

Objectives : This study evaluates the hair growth promoting effect of Yonnyuniksoogobon-dan on shaved C57BL6 mice. Methods : Yonnyuniksoogobon-dan was administered orally (Group I) and both orally and by skin application (Group II) once a day for 12 days. The experimental groups were compared to Control, which was orally administered physiological saline solution. Hair regrowth was photographically and histologically determined during the experimental period. The levels of hair growth cycle related factors (EGF, TGF-${\beta}$1) and vascular factors (VEGF, iNOS) were also determined by immunohistochemistry. On gross observation of hair growth, both Group I and Group II shaved C57BL6 mice showed accelerated hair regrowth. Results : The hair regrowth index of Group I increased significantly from 7 days (P<0.05) to 12 days (P<0.01) after shaving and that of Group II was significantly higher at 12 days (P<0.05). On histological observation, both Group I and Group II demonstrated histological improvement and increases in the number and diameter of the hair follicles. EGF expression on the root sheath of hair follicles was up-regulated in both Group I and II. TGF-${\beta}$1 expression on the root sheath of hair follicles was unchanged in both Group I and II. VEGF expression in the tissues surrounding hair follicles was up-regulated in both groups. iNOS expression in the tissues surrounding hair follicles was down-regulated in both groups. Conclusions : These results suggest that Yonnyuniksoogobon-dan promotes hair growth and this effect is related to up-regulation of EGF and VEFG expression and down-regulation of TGF-${\beta}$1 and iNOS expression on hair roots.
