February 1990 in “PubMed” This study observed that hirsute females displayed increased S-phase hair bulb cells and decreased G0/1-phase cells compared to healthy females, with a strong correlation between S-phase percentages and DHEA-S levels.
December 1990 in “PubMed” This study found that topical application of 17 alpha-propylmesterolone significantly increased proliferative activity in hair matrix cells in men with androgenetic alopecia.
