The Centers for Disease Control and Prevention (CDC) estimates that there are about 6 to 12 million cases each year in the United States among children ages 3 to 11. Frequent itching can break the skin on your head, which can lead to an infection. However, it's not realistic to expect that you and your child can avoid all contact that may cause the spread of lice. Sign-up to get Mayo Clinic’s trusted health content sent to your email.

As long as there is any hair on the head, the lice can attach to it and stay there near the warm scalp to eat their three meals a day. Head lice can only survive for up to 2 days away from the human head, so they will not last long in any surrounding areas. Fumigant spray and fogs can be toxic if inhaled or absorbed through the skin and they are not necessary to control head lice.

What about home remedies?
Technically speaking hair straighteners kill adult lice and nits, says Dr Webb, but, there's one problem here. Lice not killed by an insecticide treatment make the insecticide resistance worse. Even if you use insecticide, you have to follow up with a comb to catch the adults that survive, and then there are those that will hatch later from eggs. The only way you can catch head lice is by direct hair contact. That's why primary school students, especially those with long hair, are more likely to catch lice — they love crowding around smartphones, tablets or books together.
Step 3: Understand the Life Cycle of a Head Louse
Some experts believe prophylactic treatment is prudent for persons who share the same bed with actively-infested individuals. All infested persons (household members and close contacts) and their bedmates should be treated at the same time. Sometimes treatment doesn’t work because lice are resistant. Other times it’s because someone didn’t follow the instructions carefully enough. OTC products don’t kill nits, so application is a matter of timing. Talk to your healthcare provider if a full course of treatment doesn’t work.
While these products come from plants, research shows that some chemicals which plants make to protect themselves from insects and other pests can be toxic to humans. If using a natural product or one that you can buy without a prescription makes you feel safer, you should know that researchers have found many of these treatments can be harmful. If you recently used a lice-killing shampoo or cream rinse, it may have failed to work. This is happening in homes across the United States, leaving parents feeling anxious and worried. People who notice a rash and uneven red lines on the skin or scalp might have scabies and should see their doctor, who may prescribe a topical cream as treatment. The itchiness is the result of a local allergic reaction to the lice bites.

By crawling from one head to another, via direct head-to-head contact between two people. Lice don’t always go away after one treatment and it could take a couple of weeks to completely get rid of them. Following the treatment’s instructions leads to the best outcome. Lice and nits attach to the strands of your hair and can be hard to remove unless you use a fine-toothed comb to loosen them. After using a comb or brush, soak the comb in hot water for 10 minutes.

This includes removing head lice from hair and any personal items that may have been infested. A person can purchase medications for head lice OTC at most pharmacies. Medications include pyrethrins combined with piperonyl butoxide and permethrin lotion. 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.
How do I take care of myself?
If there's a current infestation you are likely to see eggs (known as 'nits') cemented near the base of the hair shaft, close to the scalp. Bloodsucking head lice are more of threat to a parent's state of mind than their children's health. But while these tiny, scalp-loving pests can cause plenty of irritation, itchiness, and concern, experts say that a lice infestation isn't a cause for panic.
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. Sometimes, simply combing your child’s hair to remove the lice and nits (eggs) can be effective. While time-consuming, studies show that combing injures the lice, so they rarely survive. A dermatologist can also recommend an effective treatment for your child.
Itching is an allergic reaction to chemicals in a head louse’s saliva. Not all kids will experience itching right away, but if they have had head lice before, they are more likely to start itching sooner. Catching this behavior early and treating it will help you stop a head lice problem at its roots.
Head lice are neither dangerous nor a sign of poor hygiene, and they do not spread any diseases. Some lotions and sprays come with a comb to remove dead lice and eggs. There's no need to keep your child off school if they have head lice. Treatment commonly fails if a person does not remove all the lice within a few inches of the scalp. A person may get lice after sharing objects such as hats or towels.
You’ll need to repeat this at least every 2 to 3 days until all lice and eggs disappear — but keep in mind that experts say this may not work as a standalone treatment. Whichever treatment option you choose, consider checking your hair every 3 to 14 days after applying a treatment to make sure the treatment is effective. Experts say this may happen because girls are more likely to play with their heads close together.
Generally, if no live crawling insects are seen three weeks after the treatment, it’s safe to assume that they are gone. Nits and their shells may remain in the hair for some time but won’t be viable. But there's no evidence electric lice combs have an edge when it comes to treatment, Dr Webb says. He says there is some evidence metal lice combs are better than plastic ones because they don't bend and can better scrape along the hair and remove lice.
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. However, the study in Jordan suggests that people with longer hair may get lice more frequently.
