PRP therapy for Hair Loss
PRP therapy for hair loss is a three-step medical therapy in which a person’s blood is drawn, processed, and then injected into the scalp. Some researchers suggest that PRP therapy/treatment can encourage hair growth and promote soft tissue healing.
Role of the Platelet-rich Plasma
Plasma is the liquid portion of the blood composed largely of water and proteins. It provides a medium for red blood cells, white blood cells and platelets to circulate through the body. Platelets, also called Thrombocytes, are blood cells that cause blood clots and other growth and necessary healing functions. Platelet plays a key role in the body’s natural healing process. Platelet-rich plasma, also known as Autologous Conditioned Plasma, is a concentrate of platelet-rich plasma protein derived from whole blood and centrifuged to remove red blood cells from it.
The normal PRP therapy uses injections of a concentration of a patient’s own platelets to accelerate the healing of injured tendons, ligaments, muscles and joints. In this way, PRP injections use each individual patient’s own healing system to improve musculoskeletal problems. Some medical researchers think that, similar PRP injections on the scalp can trigger natural hair growth and maintain it by increasing blood supply to the hair follicle and increasing the thickness of the hair shaft. Sometimes this approach is combined with other hair loss procedures or medications.
The PRP Therapy
The PRP therapy usually requires three treatments in 4 to 6 weeks apart. Apart from the therapy maintenance treatments are required every 4 to 6 months.
The steps involved in the therapy are as follows. Your blood is drawn from your arm and put into a centrifuge (a machine that spins rapidly to separate fluids of different densities). After about ten minutes in the centrifuge, the blood will have separated into in three layers: platelet-poor plasma, platelet rich plasma, and red blood cells. The platelet rich plasma is then drawn up into a syringe and injected into areas of the scalp that require increased hair growth.
There hasn’t been enough research to prove if PRP is an effective hair loss treatment or not. However, PRP therapy has been in use since the 1980s and has proved useful in many cases. It’s been also used for problems such as healing injured tendons, ligaments, and muscles.
