Finasteride is a pill that may regrow hair. Ask your doctor about side effects. Your hair grows back naturally in 6 to 12 months after a case of alopecia areata, but hair loss may recur. Your doctor may try to speed up regrowth by injecting your scalp with steroids or having you apply minoxidil solution directly to the bald area. Your doctor may prescribe an antifungal medication if an illness such as ringworm is the cause of your hair loss.
Hair generally grows back in the affected areas.
Hair transplant surgery involves moving sections of skin with hair from one part of the scalp to another. The results may last a few years or remain permanent. Baldness may be temporary and last only a few weeks or months. It can be permanent, however, especially if it is hereditary or the result of skin damage from a disease or burn. If you have noticeable hair loss or a change in skin condition, consult your doctor.
