Washing, soaking, or drying items at a temperature greater than 130°F can kill both
Spinosad topical suspension, 0.9%, was approved by the FDA in 2011. Since it kills live lice as well as unhatched eggs, retreatment is usually not needed. Nit combing is not required. Spinosad topical suspension is approved for the treatment of children 6 months of age and older.
Rinsing the hair with white vinegar before washing may help dissolve the glue that holds the nits to the hair shafts.
Can vinegar kill lice eggs? Vinegar is one of the classic home remedies for lice. However, if you are trying to find out how to get rid of nits using vinegar, you should know that using vinegar to kill nits or lice eggs is totally ineffective. Vinegar has no negative effect on the lice eggs.
Vinegar contains properties that kill and get rid of nits and lice. This mixture should be applied directly to the whole scalp. Mix 1 cup of vinegar with 1 cup of warm water. Next, distribute this mixture onto the scalp and cover your hair with a hair cap.
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.
Wet the entire hair with 6 parts of water plus 3 parts of vinegar. Vinegar dissolves the glue of the lice eggs, so they can easily come off the hair when combed out. Wet the entire scalp and hair from the roots down to the tips, so that you can remove dead lice eggs on hair also.
Our experience with clothes lice was similar to our experience with head lice; washing infested clothes in warm or cold water for 30 min with or without soap or washing detergent kills few lice and their eggs, although it results in clean clothes, clean lice, and clean eggs.
Hair gels, hairspray, oils or other non-medicated products do not kill lice or their eggs. Cutting your child's hair or shaving their head to get rid of lice won't keep them away. Lice stick to short and just “grown in” hair too.
Thoroughly douse your child's hair with vinegar and leave for 15 minutes to allow the vinegar to kill the lice.
Sometimes it will be easier to remove the nits if you wet the hair with white vinegar while you are combing the nits out. Vinegar helps loosen the "glue" that holds the nits to the hair. Separate and comb small sections of hair at a time.
Washing at a temperature above 130 °F will generally kill the insects. Alternately, try sealing the fabrics in plastic bags for 2 weeks. Soaking combs, brushes, and other hair care items in hot water for 5–10 minutes. Vacuuming the furniture, floor, and other surfaces that may contain lice or their eggs.
Nits are often confused with other things found in the hair such as dandruff, hair spray droplets, and dirt particles. If no live nymphs or adult lice are seen, and the only nits found are more than ¼-inch from the scalp, the infestation is probably old and no longer active and does not need to be treated.
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.
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. However, the lice could be in hiding.
Try the Apple Cider Vinegar and Olive Oil Tandem
After an hour, comb out your hair using a nit comb and pick out the lice and their eggs. Wash your hair with a little shampoo and rinse it with warm water. After that, soak your hair with the apple cider vinegar then cover it with a shower cap.
The shampoo, cream rinse, or spray kills the live lice on the head but may not kill the nits. While the nits don't need to be removed from the hair, some people use a comb to remove nits after using lice treatment because they don't like the look of nits in the hair.
Lotions and sprays for head lice and nits
There are several different products that can be applied to the scalp and hair to kill head lice, including: dimeticone 4% lotion or lotion spray – applied and left for 8 hours (usually overnight) dimeticone 4% spray gel – applied and left for 15 minutes.
Washing, soaking, or drying items at a temperature greater than 130°F can kill both head lice and nits. Dry cleaning also kills head lice and nits. Only items that have been in contact with the head of the infested person in the 48 hours before treatment should be considered for cleaning.
Use hairspray to stick it to head lice
Hairspray makes it harder for the louse to grab hold. The smell of hairspray and the use of solvents (sad but true) in them can also deter creepy crawlies from finding their way in.
