How should a comb be treated for lice? - in detail

Treating a lice comb requires a systematic approach to eliminate nits and prevent reinfestation. First, select a fine-toothed metal comb specifically designed for lice removal; plastic variants often lack sufficient rigidity to pull out eggs.

  1. Preparation

    • Wash the comb in hot, soapy water (minimum 130 °F/54 °C) for at least five minutes.
    • Rinse thoroughly and allow to air‑dry.
    • Disinfect with a solution of 70 % isopropyl alcohol or a diluted bleach mixture (1 part bleach to 9 parts water). Soak for ten minutes, then rinse.
  2. Application on the scalp

    • Dampen hair with a conditioner or a detangling spray; this reduces friction and makes the comb glide smoothly.
    • Section hair into 1‑inch strips using clips.
    • Starting at the scalp, run the comb through each section from root to tip, moving slowly to ensure the teeth capture any attached eggs.
    • After each pass, wipe the comb on a paper towel, then dip it in the disinfectant solution before the next pass.
  3. Post‑treatment handling

    • Place used combs in a sealed plastic bag for 24 hours; this time frame kills any surviving lice.
    • After the isolation period, repeat the washing and disinfecting steps before storing the comb for future use.
    • Clean any surfaces the comb touched (e.g., countertops, bathroom sinks) with the same disinfectant to avoid cross‑contamination.
  4. Maintenance

    • Perform a thorough combing session every 2–3 days for two weeks, covering the entire head each time.
    • Inspect the comb after each session; if any lice or nits are visible, repeat the disinfection cycle immediately.
    • Replace the comb if teeth become bent or corroded, as compromised integrity reduces effectiveness.

By following these steps—rigorous cleaning, proper application, secure containment, and regular re‑inspection—the comb becomes an effective tool for eliminating lice and preventing recurrence.
