Stratifying clinical response to adjuvant platelet‐rich plasma in patients with androgenetic alopecia

Abstract

Platelet‐rich plasma (PRP) is a promising treatment for androgenetic alopecia (AGA), but is not efficacious in all patients. Dynamic, quantitative trichoscopy can longitudinally follow hair regrowth during and after treatment,^1‐4 thus characterizing clinical response to PRP as continued, non‐productive treatment sessions may lead to large patient burden. To appropriately counsel patients on adjuvant PRP treatment success, clinical results must be accurately described. The objective of this study is to determine if AGA patient response to adjuvant PRP can be stratified based on quantitative hair counts after two treatment sessions.
