Mylabris is the dried body of the chinese blister beetle. The species used in medicine are Mylabris phalerata and M. cichorii. In recent studies, it has been found that Mylabris possesses antitumor properties, increases the number of leukocytes, and has irritant effects on the urinary organs. The crude extracts of Mylabris have been noted for their highly irritant action and other traditional uses of Mylabris include treatment of poor local blood circulation. The active constituent of Mylabris is cantharidin. The chemical is notable for its vesicant properties, but with severe side effects such as nephrotoxicity. This experiment examined the effect of extracts and fractions, obtained from Mylabris phalerata Pall. on hair growth activity of the C57BL/6N mice after topical application to skin. First, we examined the effect of an extracts, obtained from the alcohol extracts of dried Mylabris phalerata Pall. on hair growth activity of the C57BL/6N mice after topical application to skin. Second, we examined on hair growth activity of the cantharidin fraction of Mylabris phalerata Pall. compared to the control and 1% minoxidil groups. Third, we investigated the number of hair follicle and mast cells after topical application of extracts of Mylabris phalerata Pall. to skin for 16 days. The results were as follows: Hair growth effect from the extracts of Mylabris phalerata Pall.(0.312%) was observed in 80% of mice whose hair had been removed in 13 days. Hair growth effect from the extract of Mylabris phalerata Pall.(0.312 and 0.625%) and 1% minoxidil group was observed in 100% of mice whose hair had been clipped in 20 days. Hair growth effect from the cantharidin fraction(0.5%) and water fraction(0.5%) of Mylabris phalerata Pall. was observed in 100% of mice whose hair had been clipped in 24 days. The hair growth effect on the cantharidin fraction(0.125%) was observed to be strong compared with the minoxidil(3%) group, commercial hair growth agents, in mice whose hair had been clipped in 19 days. In the spontaneous alopecia mice model, the hair growth effect from the cantharidin fraction (0.125%) was observed to be strong as compared with the states before the 13 days experiment. These experiments suggest that extracts and fractions of Mylabris phalerata Pall. may stimulate the topical hair growth activity in low doses.
Objective : Present study was carried out to investigate the effect of Gyungohkgo-gamibang extract on hair growth and protein expression in an alopecia model of C57BL/6 mice. Methods : Mice were divided into 3 experimental groups including normal (vehicle), Gyungohkgo-gamibang extract (YNS-10) and 5% minoxidil-treated group. The test materials were daily applied with 0.1 ml per mouse on shaved dorsal skin for 3 weeks. The hair growth was monitored by photograph at 5, 10, 15, 21 days after topical application. Then the changes of hair density and hair thickness in the hair-removed area were evaluated by phototrichogram using folliscope. Also the expression level of growth factors related to hair growth was measured by western blotting. Results : Application of minoxidil or YNS-10 stimulated the hair growth compared to vehicle treatment. Therefore hair density of minoxidil or YNS-10 application was increased about 200% and 210% more than in vehicle application on 14 day, respectively. And hair thickness of both minoxidil group and YNS-10 group was increased about 220% and 210 % more than in vehicle spreading on 14 day, respectively. Futhermore the protein expression of IGF-1 and VEGF were significantly up-regulated on 7 day in YNS-10 and minoxidil-spreaded group compared to vehicle-applied group. Conclusion : These data suggest that YNS-10 has potent stimulating activity on hair growth in C57BL/6 mice and potential usefulness as ingredients of hair tonic and hairrestore.

Low-power laser(LPL) delivers a small amount of energy without elevation of tissue temperature. LPL has been reported to have biostimulation effects including anti-inflammatory, analgesic, regenerative, immunocorrective, and vasodilative effects. However, the effect of LPL on hair growth has rarely been studied. We investigated the effect of LPL on hair growth in the mouse. After depilation of back skin of mice, we classified the mice into 4 groups: control, laser irradiated group, $MoandMore^{(R)}$ applied group, and Spella $707^{(R)}$ applied group. Laser irradiation or application of these drugs were performed on the back skin of the mice for 30 days. The results are summarized as follows. Hair growth of control was first observed at 13 days after depilation, and complete hair regrowth was observed at 25 days. Hair growth of both laser irradiation group and $MoandMore^{(R)}$ applied group was first observed at 9 days after depilation, and complete hair regrowth was observed at 20 days. Hair growth of Spella $707^{(R)}$ applied group was firstly observed at the 9 days after depilation, and complete hair regrowth was observed at the 15 days. Hair growth started at the irradiation site in the laser irradiation group, but it started at the random sites in other groups. In conclusion LPL irradiation have a stimulating effect on the hair growth in the mouse.
Objectives: This study was conducted to evaluate the hair growth-promoting effects by Rumex japonicas Houttuyn ethanol extract (RJHEE) in C57BL/6N mice and HaCaT cells. Methods: The hair growth effect was examined by topical application of RJHEE on the shaved dorsal skin of C57BL/6 mice. Six-week old mice were depilated and separated in 4 groups; CON (vehicle treatment), MXD (2% Minoxidil), and RJHEE (2% and 4%). The treatments were applied daily for 17 days. The hair growth was determined photographically and the hair density, thickness and length were identified by Folliscope. In dorsal skin tissue, the expression of hair growth-related protein was analyzed by Western blotting. In HaCaT cells, the cell proliferation and the protection against H2O2-induced cell damage by RJHEE were analyzed. Results: Our results indicate that RJHEE promote the hair growth, hair density, thickness and length. RHE activate the Wnt/𝛽-catenin signaling and induced the expression of cell survival-related proteins, such as pERK/ERK and Bcl-2/Bax. In HaCaT, RJHEE accelerated the cell proliferation and protected the H2O2-induced cell damage. Conclusions: Our results strongly suggest that RJHEE promotes hair growth by regulating the activation of Wnt/𝛽-catenin signaling and cell survival signaling and protects oxidative stress-induced hair damage. Therefore, RJHEE has a hair growth activity and can be useful for the treatment of alopecia.
This study was designed to examine the effect of Lactilactobacillus curvatus LB-P9 on hair regeneration. The treatment of LB-P9 conditioned medium increased the proliferation of both hair follicle dermal papilla cells and hair germinal matrix cells (hGMCs). Moreover, the expression levels of hair growth factors such as vascular endothelial growth factor (VEGF) and fibroblast growth factor 7 were significantly elevated in hGMCs co-cultured with LB-P9. After time-synchronized depilation, mice were orally administered with either 4×107 colony forming unit (CFU) of LB-P9 (low dose) or 4×108 CFU of LB-P9 (high dose), once daily for 4 weeks. Compared with the vehicle (phosphate-buffered saline)-administrated group, the LB-P9-treated groups exhibited accelerated hair regrowth rate and enhanced hair thickness in a dose-dependent manner. Supporting this observation, both hair follicle numbers and the dermal thickness in skin tissues of the LB-P9-treated groups were increased, compared to those of the vehicle-treated group. These results might be explained by the increased level of β-catenin and number of hair follicle stem cells (CD34+ CD49f+ cells) in the skin tissues of mice administered with LB-P9, compared to the vehicle-treated mice. Also, increased serum levels of hair growth factors such as VEGF and insulin-like growth factor-1, and superoxide dismutase were found in the LB-P9-treated groups, compared to those of the vehicle-treated group. Taken together, these results might demonstrate that the oral administration of LB-P9 promotes hair regeneration by the enhancement of dermal papilla proliferation through the stimulation of hair growth factor production.
Human umbilical cord blood mesenchymal stem cells (hUCB-MSCs) are used in tissue repair and regeneration; however, the mechanisms involved are not well understood. We investigated the hair growth-promoting effects of hUCB-MSCs treatment to determine whether hUCB-MSCs enhance the promotion of hair growth. Furthermore, we attempted to identify the factors responsible for hair growth. The effects of hUCB-MSCs on hair growth were investigated in vivo, and hUCB-MSCs advanced anagen onset and hair follicle neogeneration. We found that hUCB-MSCs co-culture increased the viability and up-regulated hair induction-related proteins of human dermal papilla cells (hDPCs) in vitro. A growth factor antibody array revealed that secretory factors from hUCB-MSCs are related to hair growth. Insulin-like growth factor binding protein-1 (IGFBP-1) and vascular endothelial growth factor (VEGF) were increased in co-culture medium. Finally, we found that IGFBP-1, through the co-localization of an IGF-1 and IGFBP-1, had positive effects on cell viability; VEGF secretion; expression of alkaline phosphatase (ALP), CD133, and ${\beta}-catenin$; and formation of hDPCs 3D spheroids. Taken together, these data suggest that hUCB-MSCs promote hair growth via a paracrine mechanism.
Hair growth effects of Sangmosu have been evaluated in C57BL/6 mice. Animals were topically treated with Sangmosu (50 or $100{\;}{\mu}l/mouse$) for 40 days on the back of shaved area. Twenty days after treatment, hair growth effects were significantly observed in both female and male mice. There was no sex difference although 30 days after treatment female mice were shown to be more effective at the dose of $50{\;}{\mu}l/mouse$ than males. These data demonstrate that Sangmosu is very effective in hair growth effects in animals and thus it may be applicable to humans.
Purpose: Interest in the augmentation of hair growth for functional and aesthetic purpose has increased dramatically in recent years. Many hair growth products have been released, but most of these have not been proven scientifically. This study aims to measure the hair growth effect of azelaic acid and vitamin $B_6$, which have been known as hair growth materials, in animal models. Methods: Six weeks old C57BL/6 mice were used in this study and hair of mice were removed by topical treatment. The mice were divided into five experimental groups according to the testing material such as saline (negative control), propylene glycol(vehicle control), azelaic acid, vitamin B6 and azelaic acid plus vitamin B6 in combination. Hair growth was documented photographically and histologically, and then analysed by the high quality hair analysis program system. The quantity of endocrine factors, IGF-I and TGF-${\beta}1$ in the skin of mice was measured by PCR analysis. Results: The topical treatment of azelaic acid and vitamin B6 in combination for 2 weeks to dorsal skin accelerated hair regrowth more than other groups. The azelaic acid and vitamin $B_6$-combined treatment also promoted hair follicle elongation and thickness compared to the others. Histologic studies showed increased number of basal cells in azelaic acid and vitamin $B_6$-combined treatment. Furthermore, the azelaic acid and vitamin $B_6$-combined group significantly increased the expression of IGF-I but decreased the expression of TGF-${\beta}1$ in the skin of mice compared to other groups. Conclusion: These results suggest that azelaic acid and vitamin $B_6$, when used together, have an additive effect and might be used as hair growth materials.
