In fact, if lice fall off the head and cannot feed on human blood, they usually die within 24 hours. Knowing what head lice look like will also help you tell distinguish them from other conditions that kids get. For example, you can easily mistake flakes of dandruff for a head lice infestation if you don't know what to look for. The texture, color, and thickness of your child's hair can also make it harder to spot lice.
The louse life cycle
The most definitive sign of lice is seeing a louse on the scalp. Head lice are wingless insects roughly the size, shape, and color of a sesame seed. You may also see lice eggs (nits), which appear as dandruff-like flecks on the hair shaft. Lice eggs, also known as “nits,” are one of the first signs of a head lice infestation. Lice lay between six and ten of these nits in the hair every day, and it adds up quickly.
Alternative medicine
If OTC treatment isn't successful, you may need to see a dermatologist for assistance. Swollen lymph nodes can occur due to the excessive scratching injuring your skin, which leads to open sores and a bacterial skin infection. This causes the lymph nodes to take action to fight the infection. Excessive scratching of the eyes can cause you to develop pink eye (conjunctivitis). Unless treated properly, lice can become a recurring problem.
Symptoms
Having head lice isn't a sign of poor personal hygiene or an unclean living environment. The itchiness is the result of a local allergic reaction to the lice bites. The term nits can also refer to the empty egg casings that remain in the hair once the nymph has hatched. These are easier to see, especially on darker hair, as they are lighter, usually white or yellow.
How do you find and diagnose head lice?
See a healthcare provider if you have lice symptoms but don't see any lice or if you have problems with lice treatment. Head lice are tiny, crawling insects that live in the hair on a person’s head. The lice feed on blood sucked from your scalp and lay eggs (called nits) that firmly attach to the hair exposed at your skin’s surface (hair shafts).
When to Contact a Healthcare Provider
However, it's not realistic to expect that you and your child can avoid all contact that may cause the spread of lice. They can cause itching and irritation and can be a source of anxiety for some people. Mites are small insects that cause scabies by digging into the skin and irritating it, which makes the skin itchy. Scabies usually affects the fingers, ankles, or wrists rather than the head. It is possible to develop an infection in the sores from scratching the head. People will need to see their doctor if they get a scalp infection.
Children who have head lice don’t have to stay home from school. But as head lice spread from close contact, it’s important to tell the school, daycare center or your child’s babysitter if your child has head lice. Remind your child to avoid making head-to-head contact with other children during playtime. Adult lice lay nits (eggs) on hair shafts (where the hair projects from the scalp) and stick to the scalp. On first appearance, lice and dandruff flakes can be mistaken for one another because of their common size and yellowish-white color. Lice are parasites that attach to hair and feed on the blood of their host.
Although rare, head lice can spread through personal items like towels, sheets, hairbrushes or hats. Head lice infestations are common, affecting an estimated 6 million to 12 million people each year. Having lice does not indicate a lack of cleanliness or poor hygiene. If you have recurrent head lice, repeat the treatment, being as thorough as possible for the duration. If you're frustrated or overwhelmed, you might want to consult with a healthcare provider.
Head lice, or Pediculus humanus capitis, are long and thin. They live close to the scalp and attach to a person's hair shaft. Two weeks is the amount of time needed for adult lice and newly hatched lice to die when hot water, dryer heat, and freezing are impractical.

They are about the size of a pinhead and will be fully grown adults after about one week. That doesn’t mean that they gravitate toward people with blonde hair. There’s no evidence to suggest that lice have developed an evolutionary preference for certain hair colors.
Body lice are generally found in people living under crowded conditions with poor hygiene. Body lice are spread through direct contact with an affected person or through contact with clothing or bedding used by a person with body lice. Two treatments (spaced seven to nine days apart) often get rid of head lice. If your child or someone else in your family still has head lice after a few weeks, it means that the treatments did not work or the person got lice again. Make an appointment to see a dermatologist for help getting rid of the head lice. With proper treatment, it is possible to get rid of head lice.

To kill any lingering nits and lice, wash clothing, bedding, hats, and towels in hot water on high heat. The most prominent symptom of head lice is an extremely itchy scalp. Itching occurs as an allergic reaction to the louse bites. Finding lice in blonde hair can sometimes be a bit difficult. That’s because the lice themselves, and especially nits, can be a similar color to blonde hair. That doesn’t mean they are impossible to find, or that they prefer blonde hair over other colors.
A person is most likely to find them at the nape of the neck and behind the ears. Another difference between head lice and body lice is that body lice are generally found in the clothes and bedding of affected people. While there may be eggs attached to body hair, the nits are mainly concentrated in the seams of clothes and bedding.
Lice are tiny parasitic insects found on your head, pubic hair, and body. Even though they are slightly different, they all can attempt to live on your body and feed on your blood to survive. Head lice infest the head and neck and attach their eggs to the base of the hair shaft.
The American Academy of Pediatrics (AAP) is against "no-nit" policies that exclude children from school when they have lice.
