Head lice is a nuisance. Prevention is key! Teach your student to avoid head to head contact, including not sharing combs, brushes, hats, scarves, head bands, helmets, and pillows. And as the saying goes, "Once a week, take a peek!" This simply means once a week, parents, take a look at your student's scalp, especially behind the ears and at the nape of the neck, for evidence of lice or nits.
