How do you tell if lice eggs are alive or dead?
New eggs are attached to the hair shaft very close to the scalp. Eggs that still contain a louse embryo are brownish in color, while the empty egg shells are white to grey.
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.
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adult lice are seen, and the only nits found are more than ¼-inch from the scalp, the infestation is probably old and no longer active and does not need to be treated.
Is it necessary to remove all the nits? No. The two treatments 9 days apart are designed to eliminate all live lice, and any lice that may hatch from eggs that were laid after the first treatment. Many nits are more than ¼ inch from the scalp.
Dead nits are often black in colour and are found well away from the scalp. Nits are laid on the hair shaft within 1cm of the scalp and take about 7-10 days to hatch into head lice.
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.
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.
There are no over-the-counter or prescription treatments that totally kill both lice and nits. Nits cannot be washed out or brushed out of the hair. They must be picked or pulled out with a special nit comb or by hand.
Lice eggs (nits).
These look like tiny yellow, tan, or brown dots before they hatch. Lice lay nits on hair shafts close to the scalp, where the temperature is perfect for keeping warm until they hatch. Nits look a bit like dandruff, but aren't removed by brushing or shaking them off.
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.
Do lice eggs move easily?
Head lice eggs/nits are about the size of a pinhead. They are very firmly attached to your hair and will not move around. This lack of movement is one way that you can tell them apart from dirt, dandruff, sand, and other debris — all of which can look like nits.
Blow dry your child's hair. It has to be thoroughly dry down to the scalp to suffocate the lice. Expect this to take 3 times longer than normal drying. The dried Cetaphil will smother the lice.

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.
Lice eggs (nits) may be easier to see than live lice. They look like tiny yellow or white dots attached to the hair, close to the scalp. Nits can look like dandruff. But you can't pick them off with your fingernail or brush them away.
They will sink. The nits, which are the eggs, will float to the top of the water, they are often brown and a tear drop shape.
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.
Nits usually look yellow or white, or they can appear to be the same color as your hair, the CDC says. It's easy to confuse them with dandruff, scabs, or hair spray droplets, but nits tend to look like little grains of rice that are firmly attached to a hair follicle, Dr.
Spinosad (Natroba).
Spinosad is approved for adults and children age 6 months and older. It can be applied to dry hair and rinsed with warm water after 10 minutes. It kills lice and nits and usually doesn't need repeated treatment.
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. Keep combing until no more appear on the tissue.
Avoid head-to-head (hair-to-hair) contact during play and other activities at home, school, and elsewhere (sports activities, playground, slumber parties, camp). Do not share clothing such as hats, scarves, coats, sports uniforms, hair ribbons, or barrettes. Do not share combs, brushes, or towels.
What liquid kills lice?
Background. Dimeticone 4% lotion is an effective and widely accepted treatment for head louse infestation. However, it is a highly mobile fluid that some people find difficult to apply and is mainly left on the hair for 8 hours or overnight.
Nits take about 1 week to hatch (range 6 to 9 days). Viable eggs are usually located within 6 mm of the scalp. ) and become adults about 7 days after hatching.
Either washing done with a water temperature of at least 50 degrees C or drying is necessary to kill head lice and nits.
Lice are attracted to the blood they get through your scalp – short, long, clean or dirty. Doesn't matter! You have to clean every crevice of your house after a lice infestation.
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.
Body lice generally are found on clothing and bedding used by infested people. Sometimes body lice are be seen on the body when they feed. Body lice eggs usually are seen in the seams of clothing or on bedding. Occasionally eggs are attached to body hair.
Wash any lice-infested item in hot water that is at least 130°F (54°C), put it in a hot dryer for 15 minutes or more, or placing the item in an air-tight plastic bag and leaving it for two weeks to kill the lice and any nits. You can also vacuum floors and furniture where lice may have fallen.
They mainly stay in clothing, especially in T-shirts or shirts, and sometimes in body hair. They are never found in head hair. The eggs, often many together, are stuck with a secretion to fabric, often in the seams. Lice are most often found here.
In a normal healthy child, an infestation usually involves less than 10 live lice (7). Infestations may be asymptomatic. Itching may occur if the individual becomes sensitized to antigenic components of louse saliva that is injected as the louse feeds (7).
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.
Do dead lice eggs still stick to hair?
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.
Most treated nits (lice eggs) are dead after the first treatment with Nix. The others will be killed with the 2nd treatment. Removing the dead nits is not essential or urgent. However, it prevents others from thinking your child still has untreated lice.
The lice themselves take 7 to 11 days to hatch, so after that what is attached to the hair is the empty eggshell or the dead nit. These will stay attached to the hair and as the hair grows you will find them further and further down the hair shaft. They can stay there to the very end.
Lice attach their nits to pieces of hair, close to the scalp. If you think you have lice and see a small, oval blob on a strand of hair, it's probably a nit. 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.
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.
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.
