A Final Word About PRP and Hair Growth In my practice, the most promising use of PRP is to treat alopecia. The platelets secrete growth factors, including platelet-derived growth factor and vascular endothelial growth factor, both of which have positive effects on hair growth. Platelet-derived growth factor is one of numerous growth factors or proteins that regulate cell growth and division. In particular, it has a significant role in the formation of blood vessels (angiogenesis) and the growth of blood vessels from already existing blood vessel tissue. Vascular endothelial growth factor is a chemical signal produced by cells that stimulates the growth of new blood vessels. It is part of the system that restores the oxygen supply to tissues when blood circulation is inadequate. Before injecting PRP to treat hair loss, a tiny scalp roller with spikes is used to stimulate the thinning areas. The rationale is that this sends a message to the hair follicles to start the healing process. Then, PRP is injected over the affected area to further stimulate stem cells in the follicle. Technique Is Key As with all therapies, adequate training and experience are paramount. The beauty of the PRP technique, especially in dermatology and as an adjunctive tool in practice, is that it can be used as part of a multifaceted or layered approach. Significant clinical outcomes can be obtained with concomitant use of light therapies, fillers, and mesother-apy, as well as patient-directed home skin care regimens.
