The Application of Platelet-rich Plasma in the Treatment of Androgenic Alopecia：a Prospective Clinical Random Study.

This study included 30 patients with moderate and severe androgenic alopecia and randomly divided into two groups, group A was treated with platelet-rich plasma (once 4 weeks for 3 times) combined with external Minoxidil(5% for male, 2% for female, twice a day, 1 ml each time) , group B was treated with external Minoxidil. The patients in both groups were examined by dermoscopy before the first treatment and 1,2,3 and 6 months after the treatment. The scalp MRI was performed before the first treatment and 6 months after the treatment, the number, density and depth of hair follicles were measured to evaluate the efficacy and safety of platelet-rich plasma combined with Minoxidil in the treatment of androgenic alopecia.
