Treatment is directed at the underlying cause. Treatment may include:
Some people may choose hair grafting, or hair transplantation, to cover areas of hair loss. There are several hair-grafting techniques, which involve taking pieces of scalp from hair-growing areas on the back or side of the head and placing them into slits on the balding areas.
Wigs, hair weaves, toupees, and other hairpieces may be used to cover areas where hair is thin or absent. Other treatments may be used for other causes. Some people choose no treatment at all.
All medications may cause side effects. For example, finasteride may cause erectile dysfunction in men. Antibiotics may cause rash, stomach upset, or allergic reactions.
If treatment is successful, the hair loss stops. With male pattern baldness, treatment is often needed for life to prevent further hair loss. In some cases, treatment may allow the hair to grow back completely. Treatment may be needed for long periods of time if the underlying cause is a serious disease.
Both the affected person and the healthcare provider can frequently examine the area of hair loss to see if treatment is effective. Other monitoring depends on the cause of the hair loss. Any new or worsening symptoms should be reported to the healthcare provider.
