Efficacy of Platelet-Rich Plasma versus 5% Topical Monixidil for the Treatment of Androgenetic Alopecia

Abstract

Objective: To compare the efficacy of platelet-rich plasma (PRP) versus 5% topical minoxidil for the treatment of androgenetic alopecia (AGA). Study Design: Randomised-controlled trial. Place and Duration of the Study: Department of Dermatology, PNS Shifa Hospital, Karachi, Pakistan, from 1st November 2021 to 31st July 2022. Methodology: Seventy AGA patients aged between 18-60 years of either gender were randomly divided into two groups. Group A was given 5% topical minoxidil and Group B was given PRP. Both groups were followed up over a period of 6 months, and the final analysis was done with the help of global photography, hair pull test, and patient satisfaction score. Results: At the end of 6th month, 27 patients (77%) in Group A had a negative hair pull test as compared to only 14 (40%) in Group B (p = 0.001). In Group A, 32 patients (91.4%) reported improvement in hair scalp from baseline. Whereas, in Group B, 26 patients (74.3%) reported improvement from baseline (p = 1.00). PRP was effective in 26 patients (74.5%) and 5% topical minoxidil in 15 patients (43.7%) (p = 0.007). Conclusion: PRP therapy can be a useful alternative to topical minoxidil in the treatment of AGA.
