Head lice are small insects that live in the hair and scalp of humans. They feed on the blood of humans. The louse is the insect that lives in the hair whilst the nit is the egg that attaches itself to the hair shaft.
Contrary to popular belief, head lice is not spread by the louse jumping from one head of hair to the other. Head lice are unable to jump! The lice are usually spread when the hair comes into close contact with another head of hair.It may take up to 3 months for the symptoms of head lice to become noticeable and sometimes there are no symptoms at all. If you do suffer from them all that is likely to happen is your scalp will become itchy and irritated.
The best way to prevent an infestation of head lice is to check hair on a regular basis especially if you have children of school age, who are most likely to suffer from nits.
Head lice can be treated with specially medicated shampoo. Use this on the hair once it has been found that the hair has an infestation of lice, not just nits. You then need to wash the hair with the medicated shampoo exactly seven days after the first treatment.
