In short

Head lice are tiny insects that live on the scalp, feed on blood and lay eggs called nits that stick firmly to the hair. They spread mainly through head to head contact, are very common in school children and are not a sign of poor hygiene. Everyone in the family should be checked, only those with live lice need treatment, and treatment is repeated to catch lice that hatch from eggs.

Typical signs

  • Itching of the scalp, often behind the ears and at the back of the neck
  • Tiny white or yellow brown specks stuck firmly to hairs near the scalp
  • Live lice moving on the scalp or hair
  • Scratch marks, sores or crusts on the scalp

When to see a dermatologist

  • Lice keep coming back despite correct treatment
  • The scalp has sores, pus, crusts or swollen glands, or there is fever
  • A baby, a pregnant woman or someone with a scalp condition needs treatment
  • The scalp is scaly or has patches of hair loss
  • Itching continues even though no live lice are found

Signs vary from person to person and several skin conditions look alike. Only an examination can confirm a diagnosis.
