Head lice are insects that can be found on the head, eyebrows, and eyelashes of people. It is most common among pre-school children attending child care, elementary school children, and household members. Head lice move by crawling; they cannot hop or fly. Head lice are spread by direct contact with the hair of an infested person. Anyone who comes in head-to-head contact with someone who already has head lice is at the greatest risk.
It is very important to not share clothing items (such as hats, scarves, coats) or other personal items (such as combs, brushes, or towels).
A child may return to daycare or school the next day after treatment if no live lice or eggs remain.
