Observation of the Expression of Vascular Endothelial Growth Factor and the Potential Effect of Promoting Hair Growth Treated with Chinese Herbal BeauTop.

Despite minoxidil and finasteride already being approved by the Food and Drug Administration (FDA) for the treatment of hair loss, it is important to identify new and innovative treatments for hair loss, such as looking for a solution in Chinese herbal medicine. One such treatment to consider is BeauTop (BT), whose primary ingredients include Panax japonicus (T.Nees), C.A. Mey. (Araliaceae), Astragalus membranaceus (Fisch) Bunge (Fabaceae), Angelica sinensis (Oliv.) Diels (Apiaceae), Ligustrum lucidum W.T. Aiton (Oleaceae), Rehmannia glutinosa (Gaertn.) DC. (Plantaginaceae), and Eclipta prostrata (L.) L. (Compositae). The aim of this study was to evaluate whether BT can promote hair growth in C57BL/6 mice and to investigate hair coverage, the expression of vascular endothelial growth factor (VEFG), and the numbers of hair follicles in growth phase after oral administration. A total of 12 C57BL/6 mice were divided into two groups: control group and treatment group BT. BT was administered orally as an extract at a volume of 0.6 g/kg. The control group was treated with distilled water. Each group was treated once a day for 12 consecutive days. To observe the expression of VEGF distribution, the number of hair follicles and the hair coverage were examined on days 4, 8, and 12. By comparing the treatment group and control group, we found that VEGF in the BT group on day 8 presented with a higher area percentage than the control group (p value = 0.003). Hair follicle counting results showed that the BT group was significantly higher than the control group on day 8 (p value = 0.031). Furthermore, hair coverage was shown to be significantly increased in the treatment group BT on day 8 (p value = 0.013). Taken together, these results suggest that Chinese medicine (BT) possesses the potential effect of promoting hair growth through VEGF expression. VEGF is considered the most important mediator for the process of angiogenesis involved in hair growth development.
