Q: What is GFC hair treatment, and how is it different from PRP? A: GFC (Growth Factor Concentrate) is like the advanced, next-generation version of PRP. In regular PRP, we inject your blood platelets into your scalp. With GFC, we extract only the pure, highly concentrated growth nutrients (growth factors) from your blood in a specialized laboratory kit before injecting them. Because it is completely pure with no extra blood cells, GFC is much less painful, causes less inflammation, and gives faster results in fewer sessions.
