Only men should take finasteride. Pregnant women should not even touch the tablets because the medicine can be absorbed through the skin. The medicine can cause abnormal growth of the genitals in baby boys before they are born. If an illness is causing you to lose hair, your health care provider may prescribe medication to treat the illness. For example, your provider may prescribe an antifungal medication if a fungus, such as ringworm, is the cause of your hair loss.
Hair generally grows back in the affected areas.
If you have a case of alopecia areata, your hair will grow back naturally in 6 to 12 months. Your health care provider may try to speed up regrowth by injecting your scalp with steroids or by having you put minoxidil solution directly on the bald area. This problem can recur. 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.
