As with most procedures, there is a careful process involved in using PRP for hair regrowth, beginning with a standard blood draw from the patient’s arm. The blood is put into a machine called a centrifuge, which spins the blood tube to separate out the red blood cells from the plasma.” The plasma, which is rich in platelets, is then injected directly into the scalp at the level of the hair follicles.

The process is meticulous — with injections beginning across the scalp, approximately at every half inch over the area of thinning hair — but typically, the entire procedure takes less than a half-hour.
