Baldness or hair loss is typically something only adults need to worry about. But in a few cases, teens lose their hair, too — and it may be a sign that something's going on. Hair loss during adolescence can mean a person's sick or maybe just not eating right. Some medications or medical treatments, like chemotherapy treatment for cancer, also cause people to lose their hair. And people can even lose their hair if they wear a hairstyle that pulls on their hair for a long time, such as braids.
Losing hair can be stressful during a time when appearance really matters, but the good news is that hair loss that happens during the teen years is often temporary. Once the problem that causes it is corrected, the hair usually grows back.
