Platelet-rich plasma (PRP) therapy is an effective and proven treatment for hair loss. Blood is taken from a patient’s arm into a tube that contains a separation gel. The blood is placed in a centrifugal machine to separate the red blood cells from the plasma that contains the platelets.
The PRP containing a high concentration of platelets is then injected into areas of the scalp that show hair thinning. This stimulates hair growth by encouraging the rejuvenation of follicles and also extending the growth cycle of the hair.
Clinical data provides evidence that PRP also promotes healing by the release of cytokines and growth factors from the platelets into the areas being treated.
