In this scalp infested with head lice, there are 2 scabs from scratching and a few white nits on the hair shaft (which look like flakes of dandruff but are actually glued to the hair). Numerous tiny, white lice eggs (nits) glued to the hair shaft are seen in this person with head lice. Nits are the egg cases of lice. They are seen here firmly attached to the hair. This is a microscopic picture of the head louse.

Overview
Head lice (pediculosis capitis) are highly contagious, and the most prominent symptom of a head lice infestation includes intense scalp itching.

The human head louse is a tiny insect that feeds on human blood. The female louse lays eggs (nits) on the hair shaft close to the scalp, and they become glued to the hair shaft. The nits hatch about 8–10 days later and begin to feed with any remaining adults. The nits can stay alive for a long period of time off of the body, such as on hairbrushes, furniture, or linens.
