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 cannot jump, 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
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
• 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
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.
