Your daughter keeps getting lice eggs likely due to frequent head-to-head contact at school, missed nits during treatment that hatched later, or re-infestation from family/environment, as lice spread easily in close-knit groups, and some treatments don't kill all eggs, requiring consistent combing and sometimes retreatment to break the life cycle. Lice aren't a hygiene issue and prefer any hair, but young children's close play makes them prone to catching them repeatedly.
Head lice often return due to incomplete treatments or missed steps in the eradication process. Understanding the common reasons for re-infestation is crucial in breaking the cycle and achieving long-term relief.
Try a treatment containing dimeticone or octanediol as they work physically to kill lice that come into contact with them when the hair is saturated with product. Because they don't rely on poisoning to work this means that there is theoretically no chance for the head lice to build up a resistance.

Additional Tips for Getting Rid of Head Lice
It's possible that you are dealing with head lice that are resistant to the active ingredient in your treatment product. Consult with your pediatrician or contact a pediatric dermatologist for a prescription head lice treatment.
Getting head lice isn't a sign of poor hygiene or unclean surroundings. Head lice prefer clean hair to attach and lay their eggs. Another common misconception is that head lice can jump or fly from one person to another. Head lice only crawl, most often leading to transmission through direct head-to-head contact.
So how can you get rid of them?
A drying program was also used. Either washing done with a water temperature of at least 50 C or drying is necessary to kill head lice and nits.
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 spread mainly by direct head-to-head contact. So the risk of spreading head lice is greatest among children who play or go to school together. In the United States, head lice most often happen in children in preschool through grade school.
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.
Lice infestation is a commonly encountered disorder in emergency medicine. The louse survives from a blood meal from its host; hence, iron deficiency anemia is a theoretic possibility.
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.
You should treat again only if there are live (crawling) lice several days after treatment. Treat again after all eggs (nits) have hatched but before new eggs are produced. If your medication kills lice but does not kill eggs, treat again about a week after the first treatment (7 – 9 days depending on the drug).
How do you get rid of head lice?
The most common way to get head lice is by head-to-head contact with a person who already has head lice. This contact can be common among children playing at places like school or the home. Getting head lice is not related to cleanliness of you or your environment.
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.
Lice cannot “fall” on pillows, sheets, stuffed animals, and other bedding unless the hair that they are attached to fall. But they can't live on these surfaces, or on hats, scarves, furniture, or carpet. They also can't live on pets or any other animals. Nits can't live without a human host.
Exposing lice and nits to temperatures above 125 degrees F for 10 minutes is lethal. Most personal articles of clothing and bedding can be disinfested by machine washing in hot water or machine drying for at least 20 minutes using the hot cycle.
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.
You do not need to use regular shampoo or conditioner after the lice treatment. In fact, it is best to not shampoo again for 2 days, in order to give the medicine time to work. The medicine will kill the live lice bugs, generally within 12 hours. Comb your child's hair.
Pubic lice are different from the lice you may get on your head or body, so you won't find crabs on your scalp or skin. Conversely, you won't find head lice in your pubic area. However, pubic lice can live in other parts of your body that have coarse hair, including your: Armpits.
Identify Your Symptoms
Most people don't experience itching until they've had lice for 4-6 weeks. If you just started itching, your infestation likely began at least four weeks ago. People who have had lice before may develop itching more quickly during subsequent infestations.
Hair gels, hairspray, oils or other non-medicated hair products including dandruff shampoo will not kill lice or prevent eggs from hatching or sticking to the hair.
