Leave the shampoo on for a full 10 minutes. If you don't, it won't kill all the lice. Then rinse the hair well with water and dry it with a towel. Repeat the anti-lice shampoo in 9 days.
After 10 minutes, the medicine is rinsed off. Nix Creme Rinse® kills lice, but not the nits. It is the favored medicine because it may continue to kill newly hatched lice for a few days after treatment. A second treatment is needed on day 9 to kill newly hatched lice.
Generally, if no live crawling insects are seen three weeks after the treatment, it's safe to assume that they are gone. Nits would have hatched by that time if they were alive. Nits and their shells may remain in the hair for some time but won't be viable.
DO NOT over treat. Some louse shampoos can be neurotoxic and overuse can damage the nervous system. Wear gloves when treating more than one person with head louse shampoo. If more than two treatments are required to control an infestation, talk to the School Nurse(s) or the Health Department about alternative methods.
Do not use “just in case” Do not use more often than recommended It may take up to 24 hours for lice to die. If live lice are still present two days after treating, switch to a suffocating agent to kill the lice. Do not use household lice sprays or any other insecticidal sprays.
If they are full then they will be plump and shiny. What does a dead lice egg look like? A dead lice egg will be white or grey. As they are empty, they will be flat and dry.
After treatment, your skin may still itch for a week or more. This is because of your body's reaction to the lice. Follow-up care is a key part of your treatment and safety.
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.
Can someone have nits but no lice? It may be possible to have nits but no lice. If a person cannot find any nymphs or adult lice in the scalp and the nits are more than a quarter of an inch from the scalp, these may be dead and from an old infestation.
Heat Method:
There are recent studies that show that treatment of lice with heat can be quite effective in killing head lice. Products such as Lousebuster are very effective but even a home hairdryer can successfully treat lice.
Nits are minuscule, smaller than the head of a pin. They're hardy too, attaching on the hair shaft close to the scalp with a glue-like adhesive. This is what makes it so tough to get rid of head lice permanently.
Wet combing with cheap conditioner and a fine-tooth head lice (nit) comb is an effective way to find and remove head lice, if done properly.
How many head lice are usually found on an infested person? 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.
Not everyone feels lice moving around on their scalp, but some people do. Dr. Garcia says that most of her patients say they “don't feel anything,” but others may get a creepy, tickling sensation as lice move around their head.
Detection combing can be carried out on dry or wet hair. Dry combing takes less time, but wet combing is more accurate because washing with conditioner stops head lice from moving.
The conditioner does not kill lice but stuns them for about 20 minutes enabling easier removal. The long toothed metal comb will remove nits and the stunned head lice. Wipe the comb on a white tissue and check for any lice or nits.
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.
Nits are often confused with dandruff, scabs, or hair spray droplets. Head lice nits usually take about 8–9 days to hatch.
Leave the shampoo on for a full 10 minutes. If you don't, it won't kill all the lice. Then rinse the hair well with water and dry it with a towel. Repeat the anti-lice shampoo in 9 days.
Nits may remain after lice have gone. They are empty eggshells and stick strongly to hair. They will eventually fall out. If you prefer, a fine-toothed 'nit comb' can remove them.
If nits are yellow, tan, or brown, it means the lice haven't hatched yet. If the nits are white or clear, the lice have hatched and just the egg remains. Lice eggs hatch within 1 to 2 weeks after they're laid.
Adult head lice can survive for 2 days and nits for around 1 week on a hairbrush. Soaking combs or hairbrushes in hot water of at least 130°F (54.4°C) for 5–10 minutes will kill any lice and nits.
