Introduction: Platelet-rich plasma (PRP) has emerged as a new treatment modality in regenerative plastic surgery, and preliminary evidence suggesting that it might have a beneficial role in hair re-growth. Here, we reported the results of a randomized, trichoscan evaluator blinded, placebo half-head group study to compare the hair re-growth with PRP and with human follicle stem cells (HFSCs) versus placebo. To investigate the safety and clinical efficacy of autologous PRP injections and HFSCs for pattern hair loss.
