Autologous Platelet-Rich Plasma in the treatment of androgenetic alopecia: results of a 54-patient prospective study

The current medical treatments of androgenetic alopecia (AGA) have hardly achieved a satisfying clinical improvement. Biologic regenerative therapies, such as platelet-rich plasma (PRP) injections in the scalp, have been proposed recently.
