Efficacy of Platelet-Rich Plasma in the Treatment of Androgenic Alopecia

In 2016, a study conducted by Dhot PS, Singhal P, Sachin K, Sayal SK, Sehgal R, involved 10 patients with androgenic alopecia. Over three months, these patients received autologous Platelet Rich Plasma (PRP) injections on the affected areas at two to three week intervals. The results indicated improvements in hair counts, thickness, root strength, and overall alopecia three months post-treatment. The study concluded that PRP is a cost-effective and promising treatment for androgenic alopecia with no significant adverse effects. However, the authors noted that despite PRP's strong theoretical basis for use in hair restoration, clinical evidence was still weak and further randomized, placebo-controlled, clinical trials were needed.
