Platelet rich plasma (PRP) is concentrated blood plasma which contains approximately three to five times the number of platelets found in normal circulating blood. Platelets contain components such as platelet derived growth factor (PDGF), vascular endothelial growth factor (VEGF), transforming growth factor (TGF) and other bioactive proteins that aid in wound healing and possibly hair growth.
Growth factors in platelet rich plasma (PRP) have been used to facilitate wound healing. It has been used in orthopedics to speed recovery of tendon injuries, the treatment of osteoarthritis, in some aspects of dental work (i.e. jaw reconstruction) and in cardiovascular medicine. The concentrated form of plasma has been shown to accelerate wound healing and tissue repair and, thus, could potentially benefit hair restoration procedures. Recently, studies have suggested that PRP may also serve as a safe and effective treatment option for male and female pattern hair loss.
Platelets are a constituent of human blood, which is primarily composed of red blood cells (RBC). Other components include white blood cells (WBC), platelets, and plasma. Platelets are involved in coagulation and are integral to the body’s ability to heal wounds. It is thought that by increasing the platelet count in a wounded area, the body’s healing to that area would be accelerated – explaining the use of PRP in wound healing. Its possible effects on promoting hair growth make it potentially useful for both the medical treatment of hair loss and as an adjuvant in hair transplantation.
