How to Prevent Head Lice

  • Avoid direct head-to-head contact with people
  • Don't share brushes, combs, ribbons, hats, helmets, or hair ties
  • Keep long hair tied up or pulled back
  • Brush hair regularly with a close bristled brush


  • Lice can be resistant to pediculocides (chemical treatments- not recommended for children under 3 years of age)
  • No matter what treatment is used, all nits must be removed to eradicate lice.
  • Recommend the use of a metal nit comb and manual removal (nit picking) to remove all nits.
  • Olive oil on hair for 8 or more hours, it has its own insecticidal properties, it smothers and kills active head lice. Use it daily for up to 3 weeks.
  • Treatment is not complete until ALL nits are removed.
