Efficacy of platelet-rich plasma in treatment of androgenic alopecia.

Background: Platelet-rich plasma (PRP) has shown remarkable beneficial effects without any major adverse reactions in the treatment of androgenic alopecia. The growth factors in activated autologous PRP induce the proliferation of dermal papilla cells.
Objectives: The objective was to investigate the clinical efficacy of PRP in treatment of androgenic alopecia.
Materials and Methods: Ten patients were given autologous PRP injections on the affected area of alopecia over a period of 3 months at interval of 2-3 weeks and results were assessed.
Results: Three months after the treatment, the patients presented clinical improvement in the hair counts, hair thickness, hair root strength, and overall alopecia.
Conclusion: PRP appears to be a cheap, effective, and promising therapy for androgenic alopecia with no major adverse effects.
