Hair Loss Overview
Hair loss is extremely common, affecting about 50 million men and 30 million women in the U.S. About 50% of men will have some hair loss by the time they turn 50. Hair loss is not life-threatening, though it can have devastating psychological effects, particularly in women.
What Are Causes of Hair Loss?
Hair loss is often caused by genetics, that is, it runs in families. In general it is not a symptom of disease, however, thyroid disease, anemia, ringworm of the scalp, and anorexia can cause hair loss. In addition, some medications such as cancer chemotherapy may cause temporary hair loss. Hair growth usually returns to normal when the medications are stopped. In some cases, hormones after giving birth or during menopause can cause thinning hair.

Male-Pattern Baldness

Hair Loss Treatment
First, it is important to determine that hair loss is not caused by an underlying medical condition. If that is the case, the medical condition needs to be addressed.
If there is no medical problem causing the hair loss, treatment options include medications, surgery, grooming techniques, wigs, and hairpieces.
