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. In people with allergies, a history of scalp infections, or an injured scalp, it may not be safe to use over-the-counter lice treatments. Even if successful in killing all the adult lice, it is crucial to remove all the eggs, as they will hatch into nymphs that become adults. If the medicine seems to be working, wait a few days to wash your hair, and keep combing each day for a couple of weeks to ensure you remove all of the lice. You may need to treat again in a week to kill surviving lice that hatched after the first round of treatment.

So, if lice are not visible under a light, try washing the hair and then looking again. 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 a nuisance, but, fortunately, they do not spread disease. Unlike in the past, kids could not return to school until they were free of nits; now, experts say this is unnecessary. That's because nits are not viable and are unlikely to be transferred to others, among other reasons.

The ones up near the top appear to have just had a blood meal and look a bit darker. Here we have a woman combing hair with a lice comb under a magnifying glass. A doctor or pharmacist can help a person to choose the best method of treatment. Each year, around 6–12 million cases of lice occur in children aged 3–11 in the United States.
What Do Lice Eggs Look Like?
At that point, symptoms of itching and crawling feelings can begin, though it may take longer to notice. Adult lice will start laying eggs the moment they infest a host. This is one reason head lice inspections are recommended during school outbreaks. Nits can often be identified and treated before it gets out of control. Nonprescription and prescription medications can help treat head lice.
What Are Head Lice?
Because dead and hatched nits stick to the hair for a long time, finding nits alone doesn’t necessarily mean there’s an active lice infestation. Talk with a doctor to discuss your findings and any recent symptoms or exposures. Medicated shampoos and creams can effectively kill lice but generally won’t kill all nits with a single application. A doctor may recommend repeat treatment 7–10 days after an initial treatment to kill live nits and lice that have recently hatched. If you find brown nits, carefully check the rest of the scalp, especially the hair behind the ears and at the back of the neck.
Are lice visible to the human eye?
Let’s get this first myth out of the way right at the beginning. Head lice are a wide variety of colors including dark brown, light brown, tan, gray, red, and even translucent white! You can imagine those mostly transparent lice are especially difficult to see and they are extremely common. In fact, the AAP now states that "no healthy child should be excluded from or allowed to miss school time because of head lice." Nits that are close to your child's scalp are the most likely to be infective. They're also the ones that are thought to hatch into live lice.
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. These are often mistaken for nits, and understandably so. They are pieces of fat cells that stick to the hair shaft. They do need to be pulled out of the hair with some force, like nits, but not quite as much force is needed. Once off the hair, you will see some distinct characteristics to help you tell them apart from nits.
If you still don’t find lice but see brown nits within 1 cm of the scalp, they may be live eggs. Consult a doctor about treatment and wet combing for nit removal. 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.
How to Spot Lice Eggs (Nits)
The best prevention is to keep your personal belongings to yourself. In other words, try not to borrow anyone else's things, including combs and hairbrushes. Pubic lice are a sexually transmitted infection (STI), meaning you get them from sexual contact with an infected person. You could also get from undergarments, bath towels, bedding, or a toilet seat, but it's rare for this to happen. People don’t immediately start scratching when they get lice—here are the other symptoms to note. Pubic lice can be difficult to see with the naked eye and may require a magnifying glass to visualize the infestation.
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. The medication for head lice should be applied according to the instructions. You can also use a fine-toothed nit comb to remove dead or dying lice from your hair. 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.
You don't need to be a professional to identify head lice. Their body is made up of three parts – the head, thorax, and abdomen. Lice are insects with six legs – three on each side of the body opposite one another attached to the thorax. Like the adult bugs, super lice eggs look and function the same way, they're just immune to lice treatments.
Follow treatment instructions carefully to rid the scalp and hair of lice and their eggs. It’s possible to have lice eggs without live lice during this early incubation period. Since they’re no longer viable and won’t spread or reproduce, chemical treatments are not needed.
