TLDR Activated PRP injections are effective in treating hair loss and improving hair density.
This systematic review and meta-analysis evaluated the clinical effectiveness and safety of autologous activated platelet-rich plasma (A-PRP) injections for treating alopecia. A total of 29 human clinical studies involving 864 patients were analyzed. The majority of studies (27 out of 29) reported positive outcomes, showing that A-PRP significantly improves hair density, promotes hair regrowth, folliculogenesis, reduces hair loss, and initiates the hair cycle. The pooled analysis demonstrated a significant increase in the number of hairs per cm² and terminal hairs per cm² in treated patients compared to controls. This review supports the use of A-PRP as an effective treatment for alopecia.
