PRP ( platelet-rich plasma ) therapy for hair loss is a three-step medical treatment in which a person's blood is drawn, processed, and then injected into the scalp using a very fine needle. The Platelet-rich plasma injections administered every 2 to 3 weeks for 3 months improves the number of hairs , the thickness of those hairs , and the strength of the hair roots.
Common side effects include minor swelling, redness or soreness. Typically, most patients' side effects fade within a few hours. You may experience mild soreness or swelling that lasts for a day or two.
PRP therapy results in hair restoration by stimulating the growth of new hair from previously dormant follicles, strengthening and thickening your existing hairs. Results usually occur in 3-months and a yearly touch up is advised.
