head lice

by Priya Chatterjee

also known as: nits, pediculosis, lice

head lice are tiny insects that live on the scalp and feed on blood. they are extremely common in primary school-aged children and spread by direct head-to-head contact. they do NOT mean your child is dirty — lice actually prefer clean hair. they are annoying but harmless.

contagious

yes — spread by direct head-to-head contact only (not by sharing hats, despite the myth)

duration

lifecycle is about 3 weeks — treatment takes 2 weeks of consistent combing

common age

4-11 years (primary school age)

symptoms

  • itchy scalp (though some children have no itch at all)
  • tickling feeling on the scalp
  • small white or brown eggs (nits) glued to hair shafts near the scalp
  • live lice seen on the scalp (greyish-brown, 2-3mm long)
  • scratch marks on the scalp or back of the neck
  • difficulty sleeping (lice are more active at night)

when to see a doctor

see your GP or call 13 HEALTH (13 43 25 84) if:

  • scratching has led to a skin infection (red, swollen, weeping)
  • you have treated twice and still finding live lice
  • your child is under 6 months old
  • you are unsure if it is head lice or something else

when to call 000

call 000 immediately if:

  • head lice are never a medical emergency

home treatment

  • use conditioner and a fine-tooth nit comb to detect and remove lice (wet combing method)
  • apply a head lice treatment from the pharmacy (e.g. KP24, Moov, Banlice, NitWits)
  • follow the product instructions exactly — most require a second treatment in 7 days
  • comb through with a nit comb every 2-3 days for 2 weeks to catch any newly hatched lice
  • wash pillowcases and hats in hot water — but do NOT fumigate the house (lice die quickly off the head)
  • check all family members and treat anyone with live lice at the same time
  • myths: tea tree oil, vinegar, and mayonnaise have NOT been proven to kill lice

prevention

  • tie long hair back in braids or buns for school
  • teach children not to share hats, brushes, or hair accessories
  • check your child's hair regularly (weekly wet combing is ideal)
  • there is no preventive shampoo that works
  • notify the school or childcare so other parents can check
