Studysummary This study concluded that platelet-rich plasma injections significantly improved hair density, thickness, and scalp inflammation in both male and female pattern hair loss, with better outcomes in lower-grade cases. Our plain-language summary of this paper — not a Tressless recommendation.

In 2019, a study was conducted on 51 male and 42 female patients suffering from male pattern hair loss (MPHL) and female pattern hair loss (FPHL) respectively, to assess the effectiveness of platelet-rich plasma (PRP) treatment for androgenic alopecia (AGA). After 6 monthly sessions of PRP injections, there was a significant improvement in hair density, thickness, and hair pull test results for both MPHL and FPHL patients. The treatment was particularly effective for patients with lower levels of alopecia (Grade II and III in MPHL and Grade I in FPHL). Despite some limitations such as a small sample size and short follow-up period, the study concluded that PRP injections can be recommended as an effective therapy for varying grades of hair loss in MPHL and FPHL patients.
