Summary Background Platelet‐rich plasma ( PRP ) injections have gained popularity in dermatology practice as a treatment for hair loss. As an autologous blood product, PRP is categorized as a minimally manipulated tissue by the U.S. Food and Drug Administration ( FDA ) and thus evades extensive regulation. As a result, there is a lack of standardization of its preparation and final composition. Objective This study aims to provide a systematic review of the various PRP preparation protocols and PRP compositions utilized in clinical trials for the treatment of hair loss. Methods & Materials A review of the literature was performed using PubMed and Ovid/Medline in November 2017 using the search terms “Platelet‐Rich Plasma” and (“Alopecia” or “Hair Loss”), including all publication dates. Human clinical trials in the English language were included. Results Nineteen studies (in 15 articles) met the inclusion criteria for analysis. Only 21% of these studies reported all PRP preparation factors analyzed, and only 32% of the protocols reported the platelet count for both the initial whole blood and final PRP product. Conclusion The current reporting of PRP preparation methodology and final composition is inconsistent and insufficient to enable comparison between studies and determination of efficacy for particular treatment applications.
