The first step to curing head lice is to identify the source of the infestation. The culprit is usually a parasite known as head lice, which feeds on human blood. These tiny parasites usually live close to the scalp or behind the ears. However, they can also be found on the eyelashes or eyebrows.
Head lice are spread from person to person in close proximity, so it is important to treat the problem early. The best way to prevent head lice from spreading is to prevent close head-to-head contact at home or school. Parents should also check their children for head lice. Then, they should use a lice medicine.
Treatment for head lice can include an over-the-counter (OTC) medicine that contains permethrin or another insecticide. These medicines can be effective, but you must apply them properly to prevent lice from developing resistance. The FDA has a list of pediculicides that are approved for treating head lice.
The first step is to understand what head lice are. Lice are tiny crawling insects that live in the scalp. They feed off human blood and lay eggs called nits, which attach to hair shafts close to the scalp. They’re a common problem among children, especially in preschool and elementary school. Once infested, head lice are easily spread throughout a household.
