The probability of getting lice is highest for preschool and elementary school children due to frequent head-to-head contact, with millions getting them yearly, though anyone can get them; risk increases with close contact in groups (schools, camps) and sharing items like hats or combs, though direct head contact is the primary spread method, making household exposure a significant factor.
Policies that prevent hair and head contact between people can help. The chance of spreading head lice from items that come in contact with the hair or head is small. But you can lower your risk of getting head lice by not sharing hair items, such as brushes or things that touch the head, such as hats or scarves.
It can take 4 to 6 weeks for itching to start. You may be able to see lice, but they move quickly, avoid lights and are small. You may also see lice eggs on hair shafts. Also called nits, lice eggs stick to hair shafts.
Head lice are very contagious. They spread from person to person by close body contact, and by shared clothes and other personal items. These can include things such as coats, hats, hairbrushes, and combs.
Lice like to stay on a human host because they can't survive more than a day or two on their own. So it's less common for lice to be spread by sharing hairbrushes, bedding, clothing, hats, or head coverings. Since lice only crawl and don't jump or fly, you can't get lice from sitting next to someone with lice.
Symptoms of head lice include:
Yes, head lice can briefly live and crawl onto pillows, but they can't survive long (usually 1-2 days) without a human host for blood meals, and nits won't hatch without scalp warmth, making pillows a low risk for infestation, but washing bedding in hot water is recommended to kill any stragglers.
Head lice can affect people at any age, but they most frequently infect children ages 3 to 12 years. They are especially common among young children who share close quarters, such as in day cares and schools.
Formication is a symptom where you hallucinate the feeling of insects crawling in, on or underneath your skin. This symptom has many possible causes, including mental health disorders, medical conditions and more. This symptom is often treatable, with available treatments depending on the cause and other factors.
Adult lice can only live a day or so without blood for feeding and nymphs can only live for a few hours without feeding. Nits will generally die within a week away from the host and cannot hatch at temperature lower than that close to the human scalp.
Adult female head lice are usually larger than males and can lay about six eggs each day. Nits (lice eggs) cannot hatch and usually die within a week if they are not kept at the same temperature as those found close to the scalp. Nits take about a week (range 6 – 9 days) to hatch into nymphs (young lice).
Lice are most often spread by head-to-head contact with another person who has lice, such as sleeping in the same bed. Although they do not survive long away from a human host, lice may also be spread by wearing another person's hat or clothing, or by using another person's comb, brush, or bedding.

Why Is the Scalp Itchy Despite the Absence of Lice and Dandruff? Several factors often cause itchy scalp even without lice and dandruff, including contact dermatitis, atopic dermatitis, hives, scalp ringworm, and acne.
Contrary to popular belief, bed bugs do not actually live in hair—though they may bite at your scalp. They prefer to live in dark, secluded spaces, such as behind your bed, between furniture and walls, or within cracks on your floorboard.
There is no “season” for head lice, however it tends to peak as kids return to school in the fall and then again in January after the winter school break. Head lice favor all socioeconomic groups and make themselves at home regardless of the health, hygiene, or cleanliness of their unwilling hosts.
It is unlikely for someone to get lice from a quick hug. However, someone is more likely to contract lice from having head-to-head or hair-to-hair contact with another with head lice.
Lice rarely live on hard surfaces, and they have a life expectancy of 24 hours. However, they can stay alive long enough on items such as headphones to transfer from one head to another. To lower your risk of catching lice, advise everyone, even family members, not to share headphones and to always keep them clean.
Once you think your child is free of head lice and eggs, make sure to check them once a week. You don't need to wash clothing and bedding on a hot wash - it's unlikely to help prevent the spread of head lice.
Did you know that your eyelashes are vulnerable to lice infestation? Head lice are tiny insects that live on the scalp but occasionally are found living on the eyebrows and eyelashes. Because head lice spread easily from person to person, cases are seen often in schools, affecting all socioeconomic groups.
The most common way head lice spread is by head-to-head contact. This means your child must have been touching heads with someone who has head lice. This may happen during sports, slumber parties or play time in or outside of school.
