Comment on 'The Effect of Platelet-Rich Plasma on Female Androgenetic Alopecia: A Randomized Controlled Trial': Phototrichogram Analysis

This article is a comment on a study that assessed the effectiveness of platelet-rich plasma therapy for female androgenetic alopecia. The authors of the comment offer some considerations regarding the phototrichogram data used in the study, suggesting that the full imaging areas were not captured and that a higher magnification should be used for more robust hair density calculations. They also question the accuracy of the hair density increase reported by the authors and suggest further examination to determine the potential clinical benefits of this technique.
