Platelet rich plasma (PRP) is an extract of your own blood that contains three to five times more platelets, growth factors, and active proteins for tissue and injury healing. It has been used medically for years to accelerate wound healing; repair tendon, ligament and joint damage; heal diabetic ulcers; and help regrow muscle and bone.

The platelet-rich plasma that is injected into your scalp works to heal affected areas and stimulate reparative cells through the use of growth factors. Growth factors promote the formation of substances like collagen, which is also used in anti-aging serums.
