There will be some menthol-tingling on the scalp, and if left in too long, you can do some unnecessary damage to your hair.
Rid claims to be a ten minute treatment and in fact warns not to leave on for any longer than 10 minutes. You then have to do a 2nd treatment 7-10 days after the first one. But that does not take into account the days and hours you will have to spend combing to remove the eggs that Rid does not kill.
Parents must be careful not to overuse a prescription drug for treating lice infestations because too much could cause neurological damage, the Food and Drug Administration said yesterday. The drug, lindane, is safe when used as directed, the FDA said.
Prescription-strength lice shampoos contain harsh pesticides that can cause dry scalp or even irritation and rashes. However, the shampoo itself hasn't been found to damage hair beyond temporary dryness since users are asked to nix hair conditioner after shampoo treatment of head 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.
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.
Follow these steps for most lice medicine: Read the label to be sure how long the medicine should be left on the hair and how it should be washed out. Many medicines are left on for 10 minutes. Do not use more or keep it on the head longer than what is recommended.
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.
Dry Scalp from Lice Treatment
All over-the-counter lice treatments contain a variety of irritants – from chemicals to salt-based compounds – that cause irritation and drying on the scalp.
A second treatment is needed 7 days after the first treatment to kill any newly hatched lice before they can produce new eggs.
The head lice may have become resistant to the treatment. If the treatment used does not kill the head lice, your health care provider and pharmacist can help you be sure the treatment was used correctly and may recommend a completely different product if they think the head lice are resistant to the first treatment.
But unfortunately, the nits will not simply fall out your hair. 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.
A preventative shampoo and spray can break the life cycle. A shampoo that kills lice before they can lay eggs is critical for closing the “bridge” from one head to another. Ladibugs experts recommend parents seek effective, pesticide-free options.
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.
You can treat lice and their eggs with prescription or over-the-counter medicines. After treatment, your skin may still itch for a week or more. This is because of your body's reaction to the lice.
For example, some recommend leaving Nix® on for 4 to 8 HOURS … instead of 10 minutes. Sometimes even overnight under a shower cap.
Detection combs are special fine-toothed plastic combs that you can buy from your local pharmacy, supermarket or online. A comb with flat-faced teeth and a tooth spacing of 0.2 to 0.3mm is best. Detection combing can be carried out on dry or wet hair.
Lice lay their eggs (called nits) on the hair shaft itself. Nits adhere to your hair and will not flake off like dandruff does.
Allow the medicine to sit on the scalp as directed on the bottle and then rinse with water. 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.
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.
Spread Nix® to hair, completely saturating hair and scalp. Ensure coverage behind ears and on nape of neck. Leave solution in hair for 10 minutes.
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.
It is not usually possible to get rid of lice in one day, as an infestation needs to be treated. However, there are treatments that can help get rid of lice and symptoms caused by lice more quickly. Lice infestations must first be treated by improving the hygiene of the infected person.
Seven days after the initial visit, NIX was determined to be significantly better than RID for eradicating the lice infestation. Of the 27 subjects receiving NIX, 26 were lice free vs 14 of the 31 RID-treated subjects.
Kill head lice by washing infested articles in hot water (at least 140°F) and drying in a hot dryer. Items that cannot be laundered such as headgear, earphones, and bike helmets, can be placed in a plastic bag and put in a freezer. If the freezer is 5°F or lower, all lice and eggs should be dead within 10 hours.
