Ringworm of the scalp (tinea capitis)

Ringworm of the scalp (tinea capitis) is an infection that grows in the outer layer of the scalp and in the hair. It is caused by a fungus, not by a worm. It often looks like round bald patches, but sometimes it looks like dandruff or patches of black dots. It can be treated with prescription medicine and a special shampoo.

You can catch ringworm by touching a person or animal that has it or by sharing personal items such as hats, combs, brushes, towels, and clothing.
