An advanced kind of therapy that treats hair loss is called PRP – Platelet-Rich Plasma. It consists of drawing the person’s own blood, processing that blood, and then injecting that into the area of the person’s scalp where there is hair loss. This kind of therapy is known to stimulate the growth of hair. When PRP is injected into the scalp, direct blood supply to the hair follicle is triggered. The thickness of the hair shaft is also increased significantly. There is no surgery or medication involved at all. Usually, a person gets three treatments, spaced out between four to six weeks. There are maintenance treatments that are mandatory – once in a span of four to six months.
