There's nothing you can do to prevent head lice.

You can help stop them spreading by wet or dry combing regularly to catch them early.

Do not use medicated lotions and sprays to prevent head lice. They can irritate the scalp.

There's no need for children to stay off school or to wash laundry on a hot wash.

Treat head lice as soon as you spot them.

You should check everyone in the house and start treating anyone who has head lice on the same day.

Wet combing

Lice and nits can be removed by wet combing. You should try this method first.

You can buy a special fine-toothed comb (detection comb) online or from pharmacies to remove head lice and nits.

There may be instructions on the pack, but usually you:

  • wash hair with ordinary shampoo
  • apply lots of conditioner (any conditioner will do)
  • comb the whole head of hair, from the roots to the ends

It usually takes about 10 minutes to comb short hair, and 20 to 30 minutes for long, frizzy or curly hair.

Do wet combing on days 1, 5, 9 and 13 to catch any newly hatched head lice. Check again that everyone's hair is free of lice on day 17.

Medicated lotions and sprays

Ask a pharmacist for advice if you have tried wet combing for 17 days, but your child still has live head lice.

They may recommend using medicated lotions and sprays. These kill head lice in all types of hair.

Head lice should die within a day. Some lotions and sprays come with a comb to remove dead lice and eggs.

Some treatments need to be repeated after a week to kill any newly hatched lice.

Check the pack to see if they're OK for you or your child and how to use them.
