headlice
Itchy scalp invaders
Headlice are tiny wingless insects that live on the human scalp, feeding on blood and causing itching.
They spread through head-to-head contact, especially among schoolchildren, and lay eggs (nits) that cling to hair shafts.
An infestation requires treatment with special shampoos or combs.
Also spelled as two words: head lice.
