All About Head Lice – Nits, Nymph, and Louse

Head Lice

What are head lice?

Also called Pediculus humanus capitis, head lice are parasitic insects found on people’s heads. It is very common to have head lice.
Head lice are small insects that live and feed on blood from your scalp. Lice are light brown, leaden, or brown, and they lay eggs (nits) and attach them to your hair.

Forms of Head Lice

There are three forms of lice: Eggs (also known as nits), nymphs and adult lice.

Eggs (Nits)

Nits are the eggs of head lice. They are very small, are hard to see and often confused with the scales produced by dandruff or with the droplets of the hair fixative. Adult females of the lice deposit the nits in the root of the hair, very close to the scalp. The nits are strongly attached to the capillary root. They are of the oval form and, usually, its color is between yellow and white. The incubation period of the nits is 1 week. Eggs that are most likely to become lice are usually found 1/4 inch from the scalp.

Nymph

Nits come out of the nits called nymphs, which are similar to adult lice, but smaller. The nymphs mature and become adult lice approximately 1 week after hatching (opening eggs). To live, nymphs have to feed on the person’s blood.

Adult louse

The adult louse has 6 legs and its color is between grayish and white. In people with dark hair, the adult louse looks darker. Females, which are usually larger than males, deposit eggs. Adult lice can live for 30 days on a human’s head. To live, the adult louse needs to feed on blood. If the louse detaches from the person, it dies within 2 days.
