PRP uses the patient’s own platelet rich plasma (PRP) to treat hair loss since the plasma is extracted from the blood of the patient and it contains platelets and growth factors. It is still considered an experimental treatment. The doctor draws blood from the arm of the patient. The blood is placed in a centrifuge machine to rapidly spin the blood to split the cellular elements. Once the red and white blood cells and the plasma are separated, the surgeon uses a special microneedle to inject the PRP directly into the scalp at the hair follicle level. Many doctors feel PRP for hair loss can be combined with a hair transplant to accelerate grafted hair regrowth.
