PRF (Platelet-Rich Fibrin) can be an effective treatment for certain types of hair thinning, particularly when hair follicles are still present and producing thinner, weaker hairs rather than being completely inactive. PRF contains platelets, growth factors, fibrin, and regenerative cells that may help support follicle health, improve blood supply, and stimulate thicker hair growth over time. In my practice, we typically perform a series of six treatments spaced approximately one month apart. One of the most important things for patients to understand is that hair growth is slow. While some individuals notice changes earlier, it can take up to nine months to appreciate the full benefits of treatment, and improvement is often gradual rather than dramatic. The success of PRF depends on several factors, including the underlying cause of hair loss, the duration of thinning, age, genetics, hormonal influences, and whether follicles are still viable. An evaluation by a physician experienced in hair restoration can help determine whether PRF alone is appropriate or whether combining it with other treatments may provide a better result. In out office we typically combine it with oral/topical minoxidil and/or finasteride and red light therapy. I hope this helps! Dr. Dima
