How to disinfect a lice comb? - in detail

A lice comb must be sterilized after each use to prevent re‑infestation and eliminate residual eggs. Follow these steps for thorough decontamination.

  1. Immediate rinse – Hold the comb under warm running water. Use a soft brush or your fingers to dislodge any hair, nits, or debris lodged in the teeth.

  2. Soak in disinfectant – Prepare a solution of one part 3 % hydrogen peroxide to nine parts water, or use a commercial lice‑comb sanitizer according to the manufacturer’s instructions. Submerge the comb for 10 minutes, ensuring all surfaces are covered.

  3. Heat treatment (optional) – After soaking, place the comb on a clean towel and expose it to a hair‑dryer on high heat for 2 minutes, or bake it in an oven at 200 °F (93 °C) for 5 minutes. Heat destroys any remaining organisms that chemical agents might miss.

  4. Final rinse and drying – Rinse the comb again with hot water to remove residual chemicals. Pat dry with a lint‑free cloth and allow it to air‑dry completely before storage.

  5. Storage – Keep the comb in a sealed plastic bag or airtight container to maintain sterility until the next application.

Additional considerations

  • Avoid using bleach directly on plastic combs; it can degrade the material.
  • Replace the comb after several cycles of disinfection if the teeth become dull or warped, as damaged teeth reduce effectiveness.
  • For travelers or limited resources, a 30‑second boil in water achieves comparable disinfection without chemicals.

By adhering to this protocol, the comb remains free of lice, eggs, and bacteria, ensuring safe and effective use throughout treatment.
