Poor hygiene causes lice.
Some people think that only “dirty kids” get head lice. This is simply not true. Lice are attracted to blood, not to dirty hair. Personal hygiene or cleanliness in the home has nothing to do with getting head lice.

Pets can cause lice to spread.
Dogs, cats, and other pets do not spread lice. Lice pass from person to person through close contact with the hair or personal items of a person with head lice.

Head lice can spread disease.
Although head lice can cause symptoms such as itching or scalp sores, they are not known to spread disease. They are more of a nuisance than they are a health hazard.

Going swimming will kill head lice.
Head lice can hold tightly to human hair, even when submerged under water. Chlorine found in pool water does not kill head lice.

Lice can jump from person to person.
Lice cannot jump or fly. They can only crawl. They pass from person to person only through contact, either directly or through the exchange of a personal item such as a brush, comb, or hat.

Once you kill the lice, you’ve solved the problem.
The louse itself is not the only problem for someone with head lice. The eggs of a louse, also called nits, must also be killed. Nits will hatch after about 7-10 days and must be removed.

The best way to get rid of lice is to shave your head.
Many would consider this approach to be overkill. While shaving your head can help solve the problem, it’s a drastic and unnecessary move since so many effective treatments such as Nix^® Lice Treatment products are available.

I’ve heard that Nix^® Lice Treatment products leave a residual film on the hair and that this is causing lice to build up a resistance.
Despite resistant lice issues, Nix^® Lice Treatment is still the most effective product available over-the-counter to eliminate head lice and their eggs.
