Background : Hair care products are mainly prepared by mixing chemicals and natural extracts, such as those obtained from medicinal plants. The purpose of this study was to investigate the effects of 70% ethanolic extracts from the whole plant of Houttuynia cordata and tymosin β4 powder mixtures on the growth of HaCat cells, hair follicle dermal papilla cells (HFDPC), and 3T3-L1 cells.
Methods and Results : In the ratio of tymosin β4 more than 10% concentrations, the cell viability of HaCat and HFDPC cell were increased by higher tymosin β4 concentrations. The mixtures of 70% ethanolic extract of H. cordata and tymosin β4 had no toxicity potential to 3T3-L1 cell viability. In this test, the content of thymosin β4 was higher concentration, as the anti-inflammatory effect was increased. The lipid differentiation of 3T3-L1 cells adipogenesis rate significantly increased in a treatment concentration-dependent manner.
Conclusion : These results suggest that a optimal mixture ratio of hair growth effect was 70% ethanolic extract of H. cordata solution 50% and tymosin β4 solution 50%. This mixture solution could be used in the development of hair care products.
