ABOUT HEAD LICE Interesting fact about head lice

It is estimated that up to half a million children catch head lice each year. Also as with the common cold, anyone can catch lice. So if anyone in your family catches head lice, they are not alone, and it is certainly nothing to be ashamed about!

What are head lice?

Head lice are small insects (their size can vary depending on the stage of their development, but adults are usually between 2-3 mm long when fully grown) which vary in colour from greyish white to brown. They like to set up home in a warm head of human hair and have no preference for the type of hair, be it brunette or blonde, straight or curly, clean or dirty, head lice are not fussy. There is only one way for head lice to pass from one individual to another and this is by head to head contact. Head lice cannotjump, hop or fly from one person to another, and it is also unlikely for them to be passed on through towels, combs and chair backs.

Head lice spend most of their time on or near the scalp as they need warmth to survive. They grip on the hair by means of special claws and feed on the scalp by sucking blood.

The female louse will lay up to 8 oval shaped eggs every night, gluing them to the base of individual hairs. After about seven days a young louse (nymph) emerges, leaving behind it a white egg shell.

These white egg shells remain glued to the hair and are known as nits. The nymph will begin feeding in the same way as the adult and within about 10 days will be mature and capable of breeding.

What to look for?

Due to their size, colour and rapid movement, head lice are difficult to see. The eggs (creamy brown) are a little easier to spot and will be found attached to individual hairs near to the scalp.

In contrast, the white nits can often be seen further from the scalp, this is because as the hair grows the nits (which are still glued to the hair shaft) move with it.

The best way to find head lice and their eggs is to run a fine-toothed comb through damp parted hair looking carefully for evidence of lice. Signs to look for include faeces, cast skins or dead lice.

Louse faeces appear as black flecks like dust, often this is rubbed onto collars or the pillow at night resulting in shirts and bed clothes, becoming dirty more quickly than usual.

How to prevent head lice?

Steps that can be taken to reduce the possibility of an infection include:

•    Check whole family's hair using a fine toothed detection comb on a regular basis, for any signs of head lice. If live head lice are found it is important to trace the source of the original infection. This may be someone well known to the family, but who may not be aware that they have head lice. If this person is not identified and treated, others can be quickly infected, sometimes within hours after treatment

•    If a child in your family is found to have lice, please inform their school, other parents, Health Visitor and School Nurse.

Getting the best from this treatment

In most cases a single treatment is sufficient to eliminate head lice. Use of hair mousses, gels, sprays, 2 in 1 shampoos and conditioners immediately before treatment can reduce its effectiveness.

Lice may continue to move or twitch up to 24 hours after treatment, this is normal and not a sign of treatment failure.

There is potential for head lice to develop resistance to treatments. If you detect live lice during the 7 days after the first application, a second treatment should be given on day 7. If further treatments are required consult a doctor or pharmacist, continual repetitive treatment should be avoided.

•    Nursing or care staff who routinely use Head LiceTreatment 1% may wish to wear gloves in order to avoid possible irritation

•    If one member of the family needs treatment, it is important to check the rest of the family for head lice, and ONLYTHOSE INFECTED SHOULD BE TREATED.

•    The effect of Head Lice Treatment 1% on artificial hair

dyes and perms has not been determined, although complaints are extremely rare. It is recommended to apply the product to a small section of hair first, before treating the entire scalp.

Always use Head Lice Treatment 1% as your doctor/pharmacist has instructed you. You should check with your doctor or pharmacist if you are unsure. The usual dose is 59ml (one bottle). It is very unlikely that more than two bottles will be required per application.

Please follow these instructions carefully:

1.    Shampoo the hair with a mild shampoo. Do not use a combined shampoo-conditioner or a medicated shampoo. Rinse thoroughly and towel dry so that the hair remains damp.

2.    Shake the bottle thoroughly, apply sufficient Head Lice Treatment 1% to saturate the hair, roots and scalp.

Work methodically through the hair paying particular attention to the areas behind the ears and around the nape of the neck.

For the majority of individuals all of the contents of this pack will be required to ensure that the hair and scalp are saturated.

It is advisable to use the full bottle.

3.    Leave on the hair for 10 minutes, then rinse and comb with an ordinary comb.

An application for longer than 10 minutes will not give better results, but a full 10 minutes is required.

4.    Rinse thoroughly with water. After this final rinse and while hair is still wet, use the fine toothed comb (provided with the pack) to remove the lice and eggs. Comb the hair in sections from the roots and work over the whole head in this way.

Normal hair drying routines can then be followed.
