Hair loss from the scalp or body that can occur in people of any age and gender.

Alopecia is hair loss from the scalp or anywhere on the body. It can occur in people of any age and gender.

Symptoms of alopecia include gradual thinning on top of the head, patchy bald spots, sudden loosening of hair, and full-body hair loss.

Some people let scalp hair loss run its course. Others choose to cover the baldness. A healthcare professional can recommend medicines and surgical procedures, depending on the type of hair loss.
