The Role of Platelet-Rich Plasma Therapy in Refractory Folliculitis Decalvans

The document reports on a case series involving two male patients with refractory folliculitis decalvans (FD) who underwent platelet-rich plasma (PRP) therapy. The first patient, aged 36, saw symptomatic improvement and hair loss stabilization after four PRP sessions over four months, but the benefits were not maintained without continuous treatment. The second patient, aged 25, experienced noticeable improvement after three PRP sessions but relapsed when treatment was paused. The study suggests PRP's potential anti-inflammatory and antimicrobial effects could be beneficial for FD treatment but emphasizes the need for larger studies due to the small sample size and temporary nature of the results.
