No, actually they are not. They are annoying, they itch, they eat blood like a mosquito, defecate on your scalp, and they are disgusting...but they are not harmful.

Lice are small, wingless, grayish-white insects with flattened, elongate bodies and somewhat oval heads. They are about 1/16 to 1/8 inch long. See similar questions...

Head lice do not hop, jump or fly. They migrate through direct contact with an infested person and their belongings. Pets do not transmit head lice, and poor personal hygiene does not cause an infestation. In fact, head lice prefer clean, healthy heads. Head lice do not live in, nor spontaneously generate from, the dirt, trees or the air. They live on the human head! See similar questions...

middot; First thing is don’t panic. Lice are a nuisance and have been stigmatized; they are NOT a serious medical problem. See similar questions...

Not necessarily. If members of your family don't share personal items, and if proper cleanup measures are taken, the infestation shouldn't spread. But, it has been known to happen! See similar questions...

Head lice CRAWL very fast and require head to head contact for transmission. It is possible that because of the way young children play, head lice are seen more widely amongst primary school children than adolescents or adults. See similar questions...

When speaking about digestive enzyme formulas, no. As active protein molecules, the enzymes do not accumulate in the body. They impart enzymatic activity that lasts anywhere from one to four hours and then they are eliminated from the body or the proteins are broken down and the amino acids are used for other purposes. As with any herbal or nutritional supplement, evaluation of amounts and over consumption should be determined on an individual basis. [back to top] See similar questions...

We have not tested it on animals. Head lice (for whatever reason) only live on humans. They can be carried or transmitted by animals but they cannot live on them for more than a few days. Since this is the case, we have not tried it on animals nor do we recommend it...you can try it at your own risk if you like. See similar questions...

Unfortunately, there is also a large amount of conjecture and opinion on the internet that has claimed that fluoride is dangerous. At therapeutic levels there has never been a published study that has been able show reliable repeatable results that demonstrate even a possibility of any harm. Many people find all of the negative opinions very confusing. See similar questions...

It is difficult to track head lice cases because head lice are not considered a disease and therefore public health departments and the Centers For Disease Control do not routinely track the number of head lice cases. However, schools and manufacturers of lice products estimate head lice cases at 12- 25 million infestations a year in the United States alone. Most of those infested are children under the age of twelve. See similar questions...

The most common symptom of a head lice infestation is persistent itching, particularly around the ears, back of the neck and crown, but some people never itch at all. Repeat infestations can cause some individuals to become super-sensitive to bites. Secondary bacterial infections can occur with excessive scratching. See a doctor if this occurs. Diagnosis of head lice is usually made by finding nits (lice eggs). See similar questions...

Getting rid of head lice is a three-step process. You must kill all the live lice, check for and remove all the nits by combing and manual nit picking, and do a reasonable job of cleaning the infested person's belongings and home environment. Please make sure you have head lice before treatment. Many people misdiagnose head lice and treat themselves or their children with chemicals unnecessarily. See similar questions...

People should also be aware that according to entomologists, any insect over time can develop resistance to pesticides. It is not surprising therefore, that many consumers, health professionals and entomologists report that head lice have become resistant to pediculicides. However, failure to follow directions, non-compliance and failure to pick nits manually can also result in a persistent head lice infestation. See similar questions...

If you have used a pediculicide correctly and still have live lice or new nits, you probably have a persistent case of head lice. According to the Palm Beach County Head Lice Task Force and the Head Lice Treatment and Prevention Project at Florida Atlantic University College of Nursing, persistent head lice is defined as three incidents of live lice found over a 6-week period.
