A Spilt Head Study of Efficacy of Placebo versus Platelet-rich Plasma Injections in the Treatment of Androgenic Alopecia.


Hair loss reduced with evidence of new hair growth. Digital image analysis showed an overall improvement in hair density and quality as lanugo-like hair became thicker, normal hair. An improvement in hair density, quality and thickness on trichoscopy was noted.


Our data suggest that PRP injections have therapeutic effect on male pattern hair loss with no major side effects and high patient satisfaction overall.

The Effect of Platelet-Rich Plasma in Hair Regrowth: A Randomized Placebo-Controlled Trial.

Giusti et al. demonstrated that the optimal platelet concentration for the induction of angiogenesis in human endothelial cells was 1.5 million platelets per microliter, whereas excessively high concentrations of platelets were suggested to decrease the angiogenic potential. In this study, a mean of 1,484,555.6 platelets per microliter in the PRP preparation could effectively stimulate follicular and perifollicular angiogenesis, which is suggested to be one of the major factors in active hair growth. Our data and data published by us and other authors since 2011 suggest that the injection of PRP preparations has a positive therapeutic effect on male androgenic alopecia without major side effects.
