-------------------------- Head-Lice
What are they?
Head lice are small insects that live
on the scalp. They feed by biting the
skin and sucking blood. The lice lay
eggs and glue them to the hair close to
the scalp. The lice hatch out and the
eggshells remain attached to the hair
as it grows out. These are called nits.
Who catches them?
Head lice are most common in children
but can affect people of any age. There
are probably as many as 750,000 cases
of infestation in the UK each year!
How are they caught?
The lice are able to simply walk from
one hair to another when heads touch.
