Until you have seen lice for yourself it can be hard to know exactly what you're looking for. The first clue is itching - if your children have lice they will not be able to stop scratching, especially the back of their necks or behind their ears.
When looking in their hair you are trying to find either live lice or their eggs (known as 'nits'). The best place to look is the nape of the neck or behind the ears or anywhere on the hair line, parting the hair with a fine toothed, light coloured comb such as the special one you obtained from your chemist.
You may see live lice - little insects with six legs-crawling along hair shafts. The next step is to look for the eggs or nits.
Nits are laid along the base of a hair shaft near the scalp where it is warm - anything more than an inch from the scalp will not be a nit. They are glued to the hair itself, are a dull grey colour, measure about 3mm in diameter and are very hard to remove from the hair.
Once they have hatched the empty egg case shows up as a white pin head sized speck. If you see a lot of white scurfy skin or flakes but no live lice or nits glued to the hair shaft your children may no longer have live head lice but just old hatched eggs or dry scalps.
It sounds as though you have already used chemical treatments on your children's hair. These are available over the counter from your chemist or on prescription from your doctor. The advantage of seeing your doctor is that he or she will have current information on which preparation works best on head lice in your local area.
The chemicals used are insecticides; the commonest used are malathion or
permethrin. Head lice can develop resistance to certain insecticides which prevents them being as effective. Also as a general rule shampoo preparations which you wash off soon after applying work less well than lotions which you apply to the hair and leave on overnight.
The water based lotions are generally preferable to the alcohol based preparations which can sting the eyes and sensitive skin and can make asthmatic children wheeze.
There is a lot of debate about whether chemicals should be routinely used to treat head lice; they can be effective if used under your doctor's supervision but you may need a second application about ten days after the first to destroy any live lice hatching from eggs which were not killed by the first application.
Combing can be an effective treatment but takes up a lot more of your time and will be impossible if you children refuse to allow you to comb their hair or if they have hair which is difficult or painful to comb.
A step by step approach is:
• Inspect the hair of everyone, adult and child, living in your home for nits and live lice. If you are not sure what you are looking for ask the school nurse or GP practice nurse for some photos or to check everyone for you
• If there are live lice or nits obtain a fine toothed 'nit comb' from your local chemist if you do not already have one - this helps you to look for lice and to comb the hair effectively
• Buy a huge bottle of hair conditioner - any type will do
• For each person with head lice - apply the conditioner liberally over the entire scalp with dry or washed and towel dried hair, and comb the whole head from scalp to the end of the hair, concentrating on the hairline especially behind the ears and the base of the neck. Leave the conditioner on the hair overnight and even the next day or two if you wish. Most lice should be removed at the first or second combing.
• Repeat every day or two days. Each combing will remove more of the remaining lice and some that have hatched since your last combing
• Continue combing daily until you have found no more live lice for about one to two weeks.
• Remember to keep checking the rest of the family to make sure they are still free of lice
• Change or wash pillow cases, pyjamas, towels and hoover sofas or headrests where the people with head lice sit - try to make everyone with head lice use their own towel and not share beds or sit head to head with other members of the family during this time. Persuade anyone with long hair to tie it back to avoid contact as the head lice spread by contact between hairs. Do not share hairbrushes, combs, hair bands or pillows.
You ask about ways of stopping the head lice coming back; tea tree oil has been claimed to both kill lice and to repel them; there is little scientific data to support this.
However as it may help there are several safe ways to use tea tree oil: you can use conditioner containing tea tree oil on your children's hair or you can put a few drops of oil in the water you use to rinse their hair after washing. Lavender oil is also supposed to repel head lice and can be used in the same way.
Do not apply neat tea tree oil to the scalp, especially of you baby, as it can be toxic in high doses and can be irritating to the skin and provoke an allergic reaction in some people.
Some ideas which you may have heard about should be avoided: do not wrap your children's heads in plastic caps when they have chemical insecticides on their heads as this can lead to over heating and over absorption of the chemicals through the scalp which could be dangerous.
Vaseline has been suggested but most attempts to smother the lice with Vaseline are unsuccessful and you will find it very hard to remover the Vaseline from the hair afterwards.
We recommend readers seek personal medical attention in appropriate circumstances.
