Notes from the Editor Emeritus: Platelet Rich Plasma (PRP) in Patients with Androgenetic Alopecia (AGA): Does It Work?

This document discusses the use of Platelet Rich Plasma (PRP) therapy in patients with Androgenetic Alopecia (AGA), also known as male pattern baldness. The author notes that while PRP is gaining popularity as a treatment for hair loss, there is limited scientific evidence supporting its effectiveness. The author conducted a survey among experts in the field and found that the ideal candidates for PRP are patients with thinning but not fully bald areas. Most experts agreed that approximately 70-90% of patients will see some degree of improvement, but patient expectations should be kept relatively low. The experts also differed in their approaches to PRP preparation and activation of platelets. The author concludes that while PRP shows promise, more standardized protocols and clinical trials are needed to determine its efficacy.
