PRP therapy is a three-step process. Most PRP therapy requires three treatments 4–6 weeks apart. Maintenance treatments are required every 4–6 months. Step 1 Your blood is drawn — typically from your arm — and put into a centrifuge (a machine that spins rapidly to separate fluids of different densities).

Step 2 After about 10 minutes in the centrifuge, your blood will have separated into in three layers:

  • platelet-poor plasma
  • platelet-rich plasma
  • red blood cells

Step 3 The platelet-rich plasma is drawn up into a syringe and then injected into areas of the scalp that need increased hair growth.
