Hair Regrowth with Platelet Rich Plasma (PRP) Injections
Platelet Rich Plasma (PRP) injections have grown in popularity over recent years. These treatments are commonly used in sports medicine and orthopedic surgery practices for sports injuries, but also used in cosmetic treatments of the face as well. Almost everyone knows that we require platelets to initiate clotting when we are injured, but platelets produce growth factors to promote healing and may be critical in initiating signals to our healing cells we call stem cells.
How PRP Stimulates Hair Regrowth
Platelet Rich Plasma is obtained in the office by drawing your blood and centrifuging (spinning) at 4000+ RPM for about 15 minutes to divide the various components of blood. These include serum, red cells, platelets and white cells. This process allows a many fold increase in platelet concentration which we can utilize in several ways. The potential for PRP to be helpful in hair restoration revolves around the known benefits of platelet growth factors to promote tissue repair and improve healing. Scientists have reported that PRP promotes hair growth due to the effect of these growth factors on hair follicle stem cells. Apparently, this results in activation of hair follicle stem cells to begin the process of hair growth. Studies have been performed establishing that growth factor PDGF (Platelet Derived Growth Factor) found in PRP does promote healing and tissue repair in hospitalized patients. There are other bioactive proteins as well as VEGF (Vascular Endothelial Growth Factor) and TGF (Transforming Growth Factor) which assist in wound healing, also present in PRP. If we postulate that hair thinning is a sign of injury to the follicle, it seems logical that PRP may offer benefit for hair loss patients.
Platelet Rich Plasma will improve healing with a hair restoration procedure as well, possibly improving hair growth and rate of growth of the transferred follicles.
