PRP therapy, also known as platelet-rich plasma therapy, is a medical treatment for hair loss that consists of three stages: first, the patient’s blood is extracted, then it is processed, and last, it is injected into the scalp. Injections of platelet-rich plasma (PRP) are thought by some in the medical world to stimulate the body’s own natural process of hair development and to keep it going by boosting the amount of blood that flows to the hair follicle and thickening the shaft of the hair. This method is sometimes used with other treatments for hair loss, such as drugs or surgical procedures. Platelet-rich plasma treatment has been practised ever since the 1980s. It has been applied to treat a variety of conditions, including the mending of torn tendons, ligaments, and muscles.
