Effect of Sparassis crispa extracts on hair growth inhibition of hair-removed C57BL/6 mice
ABSTRACT
Sparassis crispa is an edible and medicinal mushroom, which commonly called the cauliflower mushroom. S. crispa is known to be a good source of food and nutraceuticals due to their rich flavors and β-glucan contents as well as a good source of antiviral and anticancer compounds. However, there have been no report on the effect on hair growth stimulation and/or growth inhibition. C57BL/6 mice the most widely used lab mouse strain were used in this animal study due to their availability and the similar hair growth cycle to human hair. In this study, hair-removed five-year-old C57BL/6 mice were used to examine the effect of S. crispa extracts(70% ethanol) on hair growth stimulation and inhibition of the mice. The extracts and control compounds were topically treated once a day for 4 weeks. The hair growth was photographically and histologically examined during the total period of 4 weeks. Hair growth of the test group was a little inhibited compared to positive (3% minoxidil) and negative control groups (water and ethanol treated groups), respectively. The whole data showed little improvement of hair growth effect of S. crispa extracts but with no real statistical significance. These results suggest that S. crispa extract has little hair growth promoting activity and more works should be done to elucidate the inhibition mechanism.
