All A to Z Topics


Head lice are tiny wingless insects that live in human hair. They are common, particularly in children.
Symptoms of head lice
In many cases, head lice cause the scalp to itch. The itching is not due to the lice biting the scalp but by an allergy to the lice.
Detecting head lice
It is very difficult to identify head lice simply by inspecting your child's head. Detection combing is a more reliable method of finding head lice.
Treating head lice
Head lice can sometimes be difficult to treat due to a high re-infestation rate and their ability to develop resistance to traditional insecticides.
Preventing head lice
A head lice infestation cannot be easily prevented. Regular detection combing - for example, on a weekly basis, is the best way to find new lice quickly.
