Between the treatments, it is advised to wet the hair and comb daily with a louse-comb to remove the hatching lice. If no living lice are found, the treatment was successful, even if nits (eggs) are visible on the hair. If living lice are still present, the treatment is repeated using an anti-louse product with a different active ingredient.
Head louse egg (nit) attached to hair shaft of host. Like most insects, head lice are oviparous. Females lay about three or four eggs per day. Louse eggs (also known as nits), are attached near the base of a host hair shaft. [11] [12] Eggs are usually laid on the base of the hair, 3–5 mm off the scalp surface.
The Center for Disease Control (CDC) estimates that six to twelve million infestations occur each year among children ages 3 to 11, and although head lice are not known to spread disease, the ...
Children with nits on their hair have a 35–40% chance of also being infested with living lice and eggs. [ 25 ] [ 26 ] If lice are detected, the entire family needs to be checked (especially children up to the age of 13 years) with a louse comb, and only those who are infested with living lice should be treated.
To diagnose infestation, the entire scalp should be combed thoroughly with a louse comb and the teeth of the comb should be examined for the presence of living lice after each time the comb passes through the hair. The use of a louse comb is the most effective way to detect living lice. [9]
Pediculosis pubis (also known as "crabs" and "pubic lice") is an infestation by the pubic louse, Pthirus pubis, a wingless insect which feeds on blood and lays its eggs (nits) on mainly pubic hair. Less commonly, hair near the anus, armpit, beard, eyebrows, moustache, and eyelashes may be involved.

Crab lice are not known to transmit disease; [citation needed] however, secondary bacterial infection can occur from scratching of the skin. Crab louse infestation can be diagnosed by identifying the presence of active stages of the louse, as well as of eggs (nits) on the pubic hair and other hairs of the body.
