CHOICE's advice

If your child is heavily infested with head lice, you might want to try an insecticide-based product before going herbal.  

Reasons why a treatment might not work

There are several reasons why a head lice product might fail to work. These include:

  • not using enough of it to adequately cover the scalp and hair
  • not repeating the treatment after 7 to 10 days (to kill eggs, which often survive the first application)
  • getting reinfested due to head-to-head contact with another person with lice
  • resistance to the active ingredient of a product.

When it comes to resistance, results can vary by region. Even if there are reports of resistance to certain insecticide ingredients, it may still work in your local area.

Misuse can contribute to lice resistance and adverse reactions, so it’s important you use treatments as directed (see Treatment tips).
