While hair loss usually affects the scalp, some conditions can cause hair loss on other areas of the body.
Alopecia areata is a disease that can cause hair loss anywhere on the body where hair grows. People who have alopecia areata often have hair loss on their scalp, but they can also lose part (or all) of their:
- Nose hairs
- Pubic hair
A few people who have alopecia areata lose all the hair on their body. When this happens, the disease is called alopecia universalis.
Frontal fibrosing alopecia is another disease that causes hair loss on the scalp and elsewhere. Some people lose their eyebrows, eyelashes, or hair on other areas of the body.
It’s also possible to keep the hair on your head and lose it elsewhere. The friction from wearing tight clothing, shoes, or socks can cause hair loss where you have continual rubbing.
