How long is my child's case of head lice contagious?

Your child's head lice are no longer contagious after lice shampoo treatment has been applied. Although there is a chance that some nits could remain on the hair, the nits themselves are not contagious. Children may return to school or childcare after the lice shampoo treatment is performed.

Your child may return to school and play after one shampoo treatment if crawling lice are gone. Check with your child’s school about their policy for lice.

Head lice is contagious until the child is free of nits and bugs.
