TLDR Platelet rich plasma was slightly more effective than no treatment for hair loss in alopecia areata patients.
In a randomized, placebo-controlled, split patch study conducted 5 years ago, 30 patients with Alopecia Areata (AA) were treated with 1-1.5ml of autologous Platelet Rich Plasma (PRP) made by double spin method into half the bald patch area and the other half with placebo. The treatment was administered once a month for 3 months. The results showed that the administration of autologous PRP led to observable improvement in 20% of the cases treated with PRP and only 3.3% of control cases. The study concluded that PRP was found to be minimally effective, but more efficacious than no treatment, and safe for AA patients.
