About Head Lice

    • A hair dryer can be used to help prevent head lice.

Head Lice Treatment

  • Procedures for Treating Head Lice
    • Examine and treat all household members at same time.
    • Use medicated rinse or shampoo for lice (Pediculocidal). If using NIX crème rinse, use after hair has been washed with shampoo, rinsed with water and towel dried. A sufficient amount should be applied to saturate hair and scalp. Leave on hair for 10 minutes. Rinse with water. If using a shampoo, apply a generous amount to dry hair, rub vigorously for 5-10 minutes, then add warm water, lather and rinse with water.
    • Use only a lice comb or long-toothed comb approved by your health room staff to remove all nits from hair. Additional removal by hand is usually necessary. Continue to comb nightly for two weeks.
    • A solution of warm water and vinegar (1:1) may be used to help loosen nits.

    Personal Articles and Environment
    • Wash all bedding, clothing and towels in hottest water and/or air dry in hot dryer (20 minutes). Toys that are slept with should also be cleaned.
    • Non-washables should be dry cleaned or sealed in a plastic bag for 2 weeks.
    • Soak all combs, brushes, etc. in hot (150° F) water and disinfectant (may use medicated shampoo or ammonia, Lysol, or other such cleansing agents) for 1 hour.
    • Vacuum carpets, upholstered furniture, bed mattresses, car seats and headrests and dispose of vacuum bag immediately.
