Background: Hair loss related syndromes are increasing due to environmental pollution and stress. 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% ethanol extracts from the flowers of Calendula officinalis, fruit body of Phellinus linteus, and the whole plant of Houttuynia cordata on the growth of CCD-986 cells, hair follicle dermal papilla cells (HFDPC), and 3T3-L1 cells. Methods and Results: All sample extracts at all concentrations, except for that from P. linteus fruit body at 500㎍/㎖, were cytotoxic to CCD-986 cells. However, none of the sample extracts were cytotoxic to HFDPC. The lipid differentiation of 3T3-L1 cells regulates hair regeneration via secretion of platelet derived growth factor. The 70% ethanol extract of H. cordata whole plant promoted hair growth. Adipogenesis rate significantly increased in a treatment concentration-dependent manner. Conclusions: These results suggest that 70% ethanol extracts of C. officinalis flower, P. linteus fruit body and H. cordata could be used for the development of hair care products.

Background : Recently, hair loss, which has been regarded as a mere means of middle-aged men due to stress and environmental pollution. The market for hair loss in Korea is about four trillion won and it is growing continuously. It is mainly made by mixing natural extracts such as medicinal plant. The purpose of this study was to investigate the effects of ethanol extracts of Houttuynia cordata Thunb. whole plant and Calendula officinalis L. flower extracts on the growth of fibroblasts, dermal papilla cells and lipid precursors, I want to try to make a materialization. Methods and Results : The cytotoxicity of each sample extracts treated with 50%, 100%, and 500 μg to fibroblasts, cell-viability were 107.3%, 109.6%, and 128.2%, respectively. The cytotoxicity of each sample to the dermal papilla cells was not observed. And the lipid differentiation of the lipogenic precursor cells which regulates the hairegeneration by secretion of the platelet derived growth factor. The 70% ethanol extracts of H. cordata whole plant and C. officinalis flower were showed promotes the hair growth activity. The lipolysis rate was significantly increased with increasing treatment concentration Conclusion : As a result of this study, in-vitro hair growth activity of herbal medicines for hair treatment material development was not shown to be toxic to each cell. And 70% ethanol extract of H. cordata whole plant stimulated lipid precursor cells inducing differentiation. As a result, the 70% ethanol extracts of H. cordata whole plant and C. officinalis flower have potential to developing hair-related product.
