Effect of Intralesional Injection of Autologous Platelet-Rich Plasma in Patterned Hair Loss

The study "Effect of intralesional injection of autologous platelet rich plasma in patterned hair loss" compared the efficacy of intradermal autologous platelet-rich plasma (PRP) in various grades of patterned hair loss with topical minoxidil and finasteride. Patients with patterned hair loss were randomized to receive either minoxidil and finasteride or PRP in addition to the above treatment. A total of 6 sittings were given to PRP group patients at an interval of 21 days each over a total period of 4 months. The results showed that hair wash test, hair pull test, V/T ratio, yellow dot test, mean hair diameter, and global photographic assessment were favorable in a significantly higher proportion of patients in the PRP group as compared to the non-PRP group. The study concluded that while minoxidil and finasteride form the backbone of patterned hair loss treatment, adding PRP can achieve clinically better results with minimal side effects.
