Platelet Rich Plasma treatments (PRP) or also called Platelet Enriched Plasma treatments (PEP) is the process of having blood drawn, put in a centrifuge (spinner) which separates the platelets out from the blood. These platelets are then injected into the scalp to thicken the existing hair, suppress further hair loss and increase new hair growth through increased circulation in the scalp.
Some hair transplant clinics in Thailand are beginning to offer PRP treatments with hair transplants or as additional services next to hair transplants.
