"PRP" stands for platelet-rich plasma – a component of your own blood with a higher concentration of platelets. Typically, PRP contains 3 to 8 times the concentration of platelets in normal blood. Platelets play a critical role in healing by releasing growth factors, which influence tissue repair in different types of cells. When used for hair restoration, the growth factors released by the platelets stimulate hair follicle growth.
PRP treatment for hair loss works by stimulating hair follicles to encourage them out of dormancy. Each PRP injection directly applies the patient's healing cells into the areas that are in desperate need of assistance with hair growth.
