Randomized Trialhigh evidence
Comparative efficacy and safety of platelet-rich plasma (PRP), injectable platelet-rich fibrin (i-PRF) and concentrated growth factors (CGF) for female pattern hair loss (FPHL): a prospective multicenter randomized clinical trial.
The Journal of dermatological treatment·December 1, 2026·PMID 42041234
Why it mattersFemale pattern hair loss is common and distressing, yet comparative data on autologous platelet therapies are scarce. This trial provides head-to-head evidence that i-PRF and CGF may offer superior hair regrowth to standard PRP, helping clinicians select the most effective option and counsel patients on expected outcomes and safety.
