Platelet Rich Plasma (PRP) therapy is a non-surgical hair restoration method that uses the growth factors within your body to help stimulate new follicles, increase blood flow and deliver nutrients to dormant or weakened hair follicles. The procedure begins with your doctor extracting a sample of your blood, which is then centrifuged to separate the platelet-rich plasma from the red blood cells. These platelets contain potent growth factors that can help promote healing and natural hair regrowth.
