Head lice (Pediculus humanus capitis) are parasites responsible for head lice infestations. They grow, live, and breed solely on the scalp and feed on blood. Lice do not fly or jump. They move about by crawling and clinging to hair with claw-like legs. Lice eggs are called nits and look like oval white cylinders. They are often confused for dandruff. Adult lice have a white-grey appearance in colour, which changes to red-brown after feeding.1
Head lice are a common problem among preschoolers and schoolchildren. Transmission occurs mainly through direct head-to-head contact. Other modes of transmission may include sharing headwear, brushes, and other objects that touch the head. There has also been a recent increase in lice transmission through children holding their heads together to take selfies.
