doctor will be able to tell for sure. He or she will probably look at a hair or
skin sample under a microscope to check for the ringworm fungus. You may have
other tests. But most of the time, none are needed.

Ringworm can come back, so be sure to throw away your
combs and brushes and buy new ones that won't spread the infection. Try to keep
your skin clean and dry. Don't share hats, combs, or brushes. If you treat
ringworm early, the hair in the bald spots will probably grow back. If you
don't treat it, the bald spots could be permanent.

ringworm can still go to school, as long as he or she is taking pills to kill
the fungus. You do not need to shave your child's head.
