The lost hair usually will grow back by itself, but slowly. Sometimes the new hair is temporarily gray or white, but after a time the original color usually returns. The natural regrowth of hair can often be sped up by having Dr. Myers inject a cortisone shot into the area of hair loss. The cortisone calms the overactive immune system that is attacking the hair follicles. It acts only in the area where it has been injected. Unfortunately, this does not prevent new areas of hair loss. However, if new areas of hair loss appear, re-growth may be helped by injecting the cortisone. Alternatively, topical medications may also be used.
