Head lice are insects that live in your hair. They are a brownish grey colour, measure just a few millimetres long and have six legs with claws to hold onto hairs. Head lice feed on blood from your scalp and are often most noticeable behind the ears and at the nape of the neck.
Lice cannot fly or jump, but they can ‘trapeze’ or crawl from person to person when there is close contact between heads (and possibly through sharing hairbrushes or combs).
Female lice lay eggs called nits, which appear as tiny white specks on hairs, close to the scalp. The eggs hatch after seven to 10 days. The empty egg cases can also be seen in the hair and are found slightly further away from the scalp. It is important to check behind the ears and at the nape of the neck when looking for a lice infestation.
Head lice are most common in children (who are more likely to share hats, brushes and combs and have long hair) but they can spread to adults.
Often there are no obvious signs of infestation. There may be blood spots, a rash or scratch marks around the hairline and neck from itching. Sometimes there is no itch at all. These symptoms appear only after several weeks of infestation, when the body develops an allergic reaction to the saliva of the lice.
Head lice are not a sign of dirty hair or poor hygiene. They are just as likely to be found in clean hair.

Advice for preventing head lice
- avoid sharing hairbrushes, combs and hats
- avoid touching heads together
- keep long hair tied back or cut hair shorter
- check your child’s scalp and hair each week
- preventative use of head lice products is not recommended because it can make head lice resistant to treatment
