Frequently Asked Questions About Head Lice

Head lice (Pediculus humanus capitis) come in three forms: the egg (called a nit), the nymph, and the adult.

Often hard to see, nits resemble tiny oval shaped seeds, yellow to white in color. They are about the size of a knot in thread, and often confused with dandruff or hair spray droplets.

Nits hatch into nymphs, the size of a pinhead.

Within a week, nymphs mature into adults, about the size of a sesame seed. They are grayish-white in color with six legs; they live for about 30 days on a person’s head, but die within a day or two when separated from the host. Female lice are usually larger than males and can lay as many as six eggs per day. A single insect is called a louse.

Lice exist throughout the world. They are most commonly found in children attending daycare, preschool, and elementary school (ages 3-11). Anyone who comes into direct contact with a person who has head lice, or with an object contaminated with lice or eggs, is at risk for getting lice. African Americans seem to get lice at a lower rate. Girls get head lice more often than boys.

Lice are found almost exclusively on the scalp, near the neckline, and around the ears. Lice and nits can sometimes be found on the eyebrows or eyelashes, but it is less common. Lice can also be transferred from direct contact with contaminated bedding, furniture, or clothing. Pets do not spread head lice.

Because head lice are most commonly found on the scalp, this is where most people experience symptoms. One of the first signs of head lice is a tickling sensation, like something is moving in the hair. Some people experience itching caused by an allergic reaction to lice bites, and some have trouble sleeping due to itching and lice movement at night. Occasionally, sores can develop on the head caused by intense scratching, and they may become infected with bacteria found on the skin.

Lice are spread through head-to-head contact. This typically occurs during play at school, on playgrounds, at home, at friends’ houses, or at camp. Personal hygiene or cleanliness in the home or school has nothing to do with getting head lice. (They love clean kids!)

Less common ways lice can spread include:

• Wearing clothing, such as hats, scarves, coats, sports uniforms, or hair ribbons recently worn by an infested person
• Using infested combs, brushes or towels
• Using a bed, pillow, or sleeping bag recently used by someone with lice, or by touching a carpet or stuffed animal where that person has been

It is not a 100% guarantee that your other children will get lice, but the risk is very high. In 80% of cases, a child passes head lice to siblings or parents. In about 20% of cases when men get lice, it is from their kids. 35% of nannies get lice from the children they care for.

Not at all. Head lice are extremely common and highly contagious — they do not discriminate across demographics. Lice actually love clean hair, so the myth that they only infest children who keep their hair dirty is untrue. A lice infestation can be disturbing, but it is not a health hazard and there is a very low likelihood of transmitting any disease. If you are not sure where to turn, trust a Hair Fairies salon to handle the issue quickly, discretely, and guilt-free.

A lice infestation can generally be diagnosed visually. Check the hair, particularly close to the scalp; look for live adult lice, as well as nits or eggs. In the early stages of an infestation, it may be more difficult to make a diagnosis with a small number of insects moving quickly through the hair. The quickest way to get a diagnosis is by trusting a trained professional — such as a Hair Fairies technician — who can identify exactly what is occurring.

It used to be commonplace for children infested with head lice to be kept home from school — it was known as a “no-nit” policy. Today, however, it is usually recommended that the child complete the school day and then go home for treatment. As long as the child starts treatment, they can return to school the next day (but should avoid head-to-head contact with other children).

Not really, and some can be harmful. The Harvard School of Public Health has stated that head lice are “resistant to permethrin and lindane” (toxic lice-fighting products now banned in California). The National Pediculosis Association (NPA) advises parents to discontinue use of head lice pesticides, which have been associated anecdotally with seizures, behavioral changes, learning issues, cancer, and skin diseases.
