PRP (Platelet-Rich Plasma) therapy is a safe way to stimulate hair growth and reduce the appearance of thinning. After your blood is drawn it is spun in a centrifuge separating the platelet rich cells from the remaining blood. The rich growth factors from your own blood is then injected into your scalp stimulate the hair follicles. A complete medical evaluation by the Dermatologist is required to see if you are an appropriate candidate. The evaluation includes a thorough history, blood work, and possibly a scalp biopsy.
