Because of this, finding nits alone doesn’t always mean there’s an active lice infestation. In a study from 2001, researchers carefully examined a group of school-aged children who had nits alone and found only 18% developed active head lice. An infestation of head lice most often affects children and usually results from the direct transfer of lice from the hair of one person to the hair of another. A head-lice infestation isn’t a sign of poor personal hygiene or an unclean living environment. No; this idea may have come about because the static electricity generated through combing dry hair can cause lice to be flicked into the air. Neither can they swim, fly or hop – they walk from head to head, during physical contact.
Treating head lice
For the reason mentioned previously, head lice cases are more prevalent in those people who rigorously shampoo their hair. So, unlike what you may have heard, head lice prefer hair that is clean over a person with poor hygiene. The active ingredients in pesticide treatments can cause unwanted side effects and they continue to lose their effectiveness at killing head lice. We recommend our all-natural head lice removal techniques and follow-up plan, but there are home remedies that some families use that can help you get rid of lice. Do your research and choose the option that fits your family best.
Prescription or over-the-counter medications and shampoos
Head lice do not crawl, jump, fly or swim and are "pretty fragile" once they get off your head, Dr Webb says. But this doesn't make finding an effective way to deal with them any less important.

Head lice stages
Check everyone you live with, or have close contact with, and start treating anyone who has head lice on the same day. Head lice in summer camps are quite common as lice tend to be more prevalent during warmer months. Learn the best tips to prevent head lice spread in camps in our article. Lice need to get to the head in the first place, so you will likely not find lice on bald head with no hair to climb on. When the odd live bug actually makes it to a bald person's head, it may start feeding on blood, but it probably won't survive long.

Yunnan verbena oil diluted with coconut oil was also effective. They do not have anything to do with dirty hair and are picked up by head-to-head contact. Afterward, people should use a nit comb to remove any dead or live lice that remain as well as the eggs.

The researchers found that the EO/PL solution was twice as effective as the P/PB solution, killing 100% of the lice and their nits. You’ll need to apply most smothering agents regularly for a few days or weeks for them to be effective. You can purchase many smothering agents at drugstores or grocery stores. Some treatments labeled as lice sprays often contain these ingredients and natural insecticides like permethrin. Weakening the glue-like substance results in cutting off oxygen to the nits, reducing the stickiness of the outer shell coating, or damaging the nit shell and killing the louse inside.
The itchy truth: What to know about head lice
If these methods don’t get rid of head lice, your doctor may recommend trying lindane 1%. As this treatment is strong, experts only recommend it if others treatments are ineffective. If you use too much, or swallow some by mistake, it may harm your brain or nervous system. Unlike other white or clear residues from dandruff or hair care products, nits stick firmly to the hair shaft and don’t easily come off. After treatment, the AAP recommends manually removing dead nits from the hair. You can do this by wetting the hair with water and using a fine-tooth nit comb to carefully comb through each section from the scalp to the ends.
If someone in your household gets head lice, check all family members regularly for the next couple of weeks to be sure they haven't acquired them, too. Head lice are mainly down near the scalp where they feed and lay their eggs. And you cannot put a hair straightener too close to your scalp because you will risk burning yourself. Technically speaking hair straighteners kill adult lice and nits, says Dr Webb, but, there's one problem here.
One advantage for children with long hair is that they can and should comb it up and wear it up in a bun if they are around others who may have a lice infestation. If you suspect a child has lice, preventing close contact with that child helps more to prevent the spread of head lice than having short hair. Head lice are spread primarily by direct head-to-head contact. So the risk of spreading head lice is greatest among children who play or go to school together. In the United States, cases of head lice most often occur in children in preschool through elementary school. Adult lice are about the size of a sesame seed and are tan to grayish-white.
Adults can lay up to eight nits daily and live up to a month on your scalp. Without a blood meal several times daily, an adult louse will die within a few days. Head lice and head lice nits are found almost exclusively on the scalp, particularly around and behind the ears and near the neckline at the back of the head. Head lice or head lice nits sometimes are found on the eyelashes or eyebrows but this is uncommon. Head lice hold tightly to hair with hook-like claws at the end of each of their six legs.
Storing clothing items in proximity also can lead to indirect transmission. Sharing school locker or hook space, or hanging multiple hats or scarves in the same place, could result in indirect transmission. Estimates suggest that each year, between 6 and 12 million infestations affect kids ages 3 to 11 in the United States. For this reason, the AAP doesn’t recommend “no-nit” school exclusion policies. Speak with a medical professional before you use a pediculicide.
Head lice are neither dangerous nor a sign of poor hygiene, and they do not spread any diseases. It usually takes about 10 minutes to comb short hair, and 20 to 30 minutes for long, frizzy or curly hair. When you've finished combing the hair, comb through all the hair again for a second time. In order to get rid of a case of lice, one has to be able to recognize nits and then know how to extract them from the hair. Keep in mind that because anyone with hair can get lice, everyone in the family should be checked. More potent medications may have additional side effects and risks, like itching or burning skin and eye irritation.
