So if you look on the scalp and see no visible adult lice and several small
The most common symptom of any type of lice is itching. Lice bites cause an allergic reaction that causes this itchy feeling. However, you may not feel itchy right away, especially if it's a light infestation. You may not notice any symptoms for up to six weeks the first time you get lice.
When a person has head lice for the first time, itching may not occur for 4 to 6 weeks. Lice on scalp. You may be able to see the lice, but they're often hard to spot because they're small, avoid light and move quickly. Lice eggs (nits) on hair shafts.
Children diagnosed with live head lice do not need to be sent home early from school; they can go home at the end of the day, be treated, and return to class after appropriate treatment has begun. Nits may persist after treatment, but successful treatment should kill crawling lice.
After the first treatment, when the egg-laying lice are eliminated, you are no longer contagious. To stop the cycle of lice you must stop the egg laying first, then remove the nits. Timing is everything and you must complete the 3 well-timed treatments to ensure you are lice-free.
Once you are aware of the lice exposure immediately wet the child's hair and begin to comb through the hair with a fine-tooth comb while removing any lice you see manually. It is extremely important to take action right away to keep the lice from moving deep in the hair and spreading quickly.
After each treatment, checking the hair and combing with a nit comb to remove nits and lice every 2–3 days may decrease the chance of self–reinfestation. Continue to check for 2–3 weeks to be sure all lice and nits are gone. Nit removal is not needed when treating with spinosad topical suspension.
When a case is mild, that means that it was discovered when there are 1 or 2 lice in the hair and there may be several nits that they laid. A louse lays 6-10 eggs per day for the 30 days that it lives.
While itching is a primary symptom of head lice, and most people associate head lice with an itchy scalp, many people are surprised to find they have lice but no symptoms—at least for the first few weeks of an infestation.
Each louse is only about the size of a sesame seed, so they can be hard to spot. Lice lay their eggs, called nits, on hairs near the scalp, so they're even harder to see.
The oval-shaped eggs often look yellow or white but may be the same color as your hair. They are found on the first 1-2 inches of hair shaft closest to the scalp (not the end) and are hard to remove. You may confuse them with dandruff or flakes from hairspray build-up. Head lice nits usually hatch in 8 to 9 days.
Typically, 10–15 head lice are found. The number of lice often depends on personal hygiene, for example, how often the person bathes, shampoos, or changes and washes his/her clothing.
Usually, you would have to be in head-to-head contact with a person who has lice. This can be common in schools or kindergartens, where children are often close together. Sharing combs, brushes, towels, hats, and other personal items can hasten the spread of head lice.
Adults are not immune to head lice. In fact, if you have any close contact with children or even parents of children you can be at risk of catching them if they have them. Lice transfer primarily through head to head contact, so you would have to get close to the other person.
Head lice are spread most commonly by direct head-to-head (hair-to-hair) contact. However, much less frequently they are spread by sharing clothing or belongings onto which lice have crawled or nits attached to shed hairs may have fallen.
It's possible that the nits are leftover from a previous infestation and are no longer viable, which means they are dead and won't hatch. It's difficult to tell the difference, so you should still treat any nits you find, even if there are no lice.
THE INFESTATION
An infestation with lice is called pediculosis. In a normal healthy child, an infestation usually involves less than 10 live lice (7). Infestations may be asymptomatic.
In the United States, infestation with head lice (Pediculus humanus capitis) is most common among preschool- and elementary school-age children and their household members and caretakers.
Use heat. Wash any items used or worn by the person in hot water, and dry them on high heat. Lice and nits die when exposed to temperatures higher than 130 F for more than 5 minutes. Wash anything that touched the person's skin or scalp, including jackets, hats, scarves, pillowcases, sheets, and headbands.
Repeat treatment every day or every other day for 2 weeks. Some lice eggs (nits) survive head lice treatments. The only way to be sure that lice won't come back is to pick out all nits. Nits left on the hair can hatch and cause a new case of head lice.
If you do not comb out all the remaining nits, they will hatch and restart the cycle in 7-10 days from that point. That's why we recommend 3 treatments over a 12-day period of time. This stops the life cycle of lice. These are nits at different stages and a louse.
Use fingers to separate hair and create a part. The part should allow you to clearly see the person's scalp. Look for lice crawling on the scalp where the hair is parted or on the hair shaft. The lice will be dark in color and the size of a poppyseed.
To confirm a case of head lice, you need to find live lice. Children can have a few nits without actually having a case of head lice. Usually children have no more than 10 to 20 live lice.
