If you have lost a small piece of hair on the top of your head, consider the possibility of baldness. You can pull the hair around the baldness with your hand to see if there is any hair loss, if there is no hair loss, it means that the baldness is not in the progressive stage, so you do not need to treat it, because baldness is self-limiting. If you have hair loss around the hair, consider taking oral compound glycopyrrolate, etc. If there is hair loss around the area, the disease is considered to be in the active stage, and small doses of oral glucocorticoids, such as prednisone tablets, methylprednisolone, etc., should be taken orally or topically with the above drugs. As baldness is an autoimmune disease, it is best to check liver function, thyroid, etc. At the same time, patients with baldness should pay attention to rest, avoid anxiety, avoid exertion, and pay attention to relieving their psychological stress.
