Objectives : This study was performed to determine the transdermal effects of ethanol extract from medicinal herbal mixture (SHJ) on hair growth in C57BL/6 mice and melanogenesis in melanoma cells.
Methods : Mice were divided into 3 experimental groups including vehicle (CON), SHJ extract and 5% minoxidil (MNXD, positive control)-treated group. SHJ was applied topically on the hair-shaved skin of C57BL/6 mice everyday for 15 days. The thickness and density of hair with a folliscope and morphometry of hair follicle with a H&E staining were monitored at last day. Also then, hair growth-associated gene expressions were measured by immunoblot assay.
Results : The MNXD or SHJ-treated group promoted on hair growth compared to that of vehicle-treated group (CON). Hair density and thickness of MNXD or SHJ treated-group increased compared to that of vehicle application on the 15 days, respectively. Induction of insulin-like growth factor (IGF)-1 and vascular endothelial growth factor (VEGF) were also accelerated by application of SHJ extract compared to those of CON group. But expression of transforming growth factor (TGF)-¥â1 decreased in SHJ treated-group compared to that of CON group. Furthermore, SHJ extract showed to increase melanin contents in a dose-dependent manner. Tyrosinase activity significantly increased in SHJ-treated group compared with CON group in dose-dependant manner.
Conclusions : These results suggest that SHJ can be used as a component of cosmeceuticals for hair care via promoting growth and melanogenesis of hair.
