There are pro-active measures that can be taken. Keeping the hair tied back is very important. It closes the bridge of opportunity that invites lice to spread. Discourage the use of sharing items that regularly come into contact with the head ex: brushes, combs, hair accessories, hats, scares etc. Several natural oils are believed to repel lice. Using these oils daily can help but not guarantee the chance of an infestation. The best way to ensure your child does not get re-infested is if everyone around them is lice free. Communication is the key to prevention and early detection. Be a friend tell a friend.
