Platelet-rich plasma vs. minoxidil in androgenetic alopecia treatment

According to a study published in the Journal of Drugs in Dermatology, platelet-rich plasma (PRP) therapy may be more effective than minoxidil in treating androgenetic alopecia (AGA). In this randomized controlled trial, the investigators evaluated the efficacy of PRP vs. 5% topical minoxidil for the treatment of AGA in 72 patients from a single institution. Patients were treated with either therapy for 12 weeks. 

At the beginning of the trial, the average hair count per patient in the PRP group was 83.5 ± 39.63 hairs/cm2 and the average hair count in the minoxidil group was 88.94 ± 36.09 hairs/cm2. All patients were positive for hair pull tests. After 12 weeks of treatment, hair pull tests were negative for 91.7% of the PRP group and 69.4% of the minoxidil group. The authors conclude that PRP therapy demonstrated a higher efficacy compared to minoxidil for treating AGA.
