Evaluation of adding platelet‐rich plasma to combined medical therapy in androgenetic alopecia

Abstract Background Androgenetic alopecia (AGA) is a common hair loss disorder. Objectives To evaluate the therapeutic effects of platelet‐rich plasma (PRP) in androgenetic alopecia. Methods This study was done on 126 AGA patients, 42 patients survived as control group who received medical treatment, only other 84 patients were subdivided into two groups, and they received PRP sessions as co‐adjuvant therapy using different methods administration. Patients were evaluated clinically, by dermoscopy and by digital dermoscopy to measure hair density and diameters before and after treatment. Results PRP‐treated patients showed statistically significant increase in hair density and diameter measurements than control group. These results increased by using microneedling as a method of PRP administration. Conclusion In AGA, the addition of “PRP with microneedling” to the combined medical treatment increases its efficacy and shortens the time needed for optimum improvement. Study design Single‐blinded randomized controlled study.
