Efficacy assessment of hair ampoule containing human hair follicle stem cells in hair loss reduction in women with androgenetic alopecia

Abstract

Androgenetic alopecia is characterized by the thinning and progressive hair loss due to the action of androgen hormones, causing the miniaturization of follicles and altering hair cycle. Objective: To assess the efficacy of a topical hair ampoule containing human follicle stem cells, in women with androgenetic alopecia. Methods: We used phototrichogram and image analysis to determine investigational product's efficacy compared to placebo after four months of treatment. Results: There was significant increase in the percentage of anagen hair (34.99%) and a decrease in the percentage of telogen hair (16.59%) for the treated group, what did not occur for the placebo group. There was significant increase in the scalp coverage for the treated participants after four months of product use (33.6%). Conclusions: The topical investigational treatment was effective to improve hair loss in female androgenetic alopecia after four months of treatment
