Platelet-Rich Plasma (PRP) is used for hair treatment because it contains growth factors and proteins that promote hair growth and healing. PRP is derived from the patient’s own blood, which is processed to concentrate the platelets. These platelets release growth factors that can stimulate the hair follicles, improve blood supply to the scalp, and encourage new hair growth. PRP therapy is a natural and minimally invasive option that has shown promising results in treating hair loss.
