Effect of PM extract on anagen elongation and catagen entry in human hair follicle organ culture model. Human hair follicles (20 hair follicles/group) were treated with 2 μg/ml, 20 μg/ml and 50 μg/ml of PM extract and 50 μM of minoxidil. After 6 days of incubation, hair follicle morphology was assessed following hair cycle scoring criteria. a Representative images of hair follicles for each experimental group. b Calculated ratio of anagen, early categen, late catagen
