We can't get rid of lice, how? - briefly
Effective control requires a medicated shampoo or lotion with permethrin or dimethicone, thorough combing using a fine‑toothed nit comb, a repeat treatment after 7–10 days, and washing all bedding and clothing in hot water.
We can't get rid of lice, how? - in detail
Lice infestations persist because eggs (nits) adhere tightly to hair shafts and survive many treatments. Successful eradication requires a systematic approach that targets both live insects and their eggs, removes residual contamination, and prevents re‑infestation.
First, select a proven pediculicide. Prescription‑strength products containing 1% permethrin, 0.5% malathion, or 0.05% ivermectin have demonstrated high efficacy. Follow the label precisely: apply to dry hair, saturate the scalp, leave for the recommended duration, then rinse thoroughly. Do not shorten exposure time, as it reduces kill rates.
Second, eliminate nits mechanically. Use a fine‑toothed lice comb on wet, conditioned hair. Divide hair into sections, comb from scalp outward, and wipe the comb after each pass. Repeat the combing process at least three times over a seven‑day period to capture any eggs that hatch after the initial treatment.
Third, cleanse the environment. Wash clothing, bedding, and towels used within the previous 48 hours in water ≥ 60 °C or seal them in a plastic bag for two weeks. Vacuum carpets and upholstered furniture; discard items that cannot be laundered.
Fourth, monitor and retreat. Inspect the scalp daily for live lice or viable nits. If any are found after 7–10 days, repeat the chemical treatment once more, adhering to the same protocol. Most regimens recommend no more than two applications within a 14‑day window.
Finally, educate all contacts. Inform family members, classmates, and caregivers about the treatment schedule and hygiene measures. Encourage them to perform simultaneous checks and, if necessary, apply the same regimen to avoid cross‑contamination.
Key steps summarized:
- Apply an effective pediculicide according to instructions.
- Comb out nits with a lice comb, repeating every 2–3 days for a week.
- Launder or isolate personal items at high temperature.
- Re‑inspect and repeat treatment if live lice persist.
- Coordinate treatment among all potentially exposed individuals.
Adhering to this comprehensive protocol eliminates the infestation and minimizes the chance of recurrence.
