PRP works by stimulating newly implanted or inactive hair follicles into an active growth phase. Your blood contains small cells called platelets that help stop bleeding. Platelets also contain specific growth factors that when “activated” promote tissue regeneration and healing. These same growth factors may help hair grow or slow hair loss. Blood is drawn and then spun in a centrifuge, which has the effect of separating the platelet rich plasma from the rest of the blood. Local anesthesia is administered to the scalp so the patient feels no pain. The platelet rich plasma is then injected into the scalp. No sedation or medication is required. Early data suggests a regime of every nine to eighteen months is needed to achieve optimal stimulating results.
