What is the best method to get rid of lice? - briefly
The most reliable approach uses a 1 % permethrin lotion applied to dry hair, left for the recommended time, then rinsed and followed by meticulous combing with a fine‑toothed nit comb; a second application after 7–10 days eliminates any newly hatched lice. Maintaining clean bedding, clothing, and personal items prevents re‑infestation.
What is the best method to get rid of lice? - in detail
Effective lice eradication requires a combination of precise identification, targeted chemical or mechanical treatment, and thorough environmental control.
Accurate detection involves close visual inspection of the scalp and hair. Use a fine-toothed comb on wet, conditioned hair to separate strands. Examine the comb teeth after each pass for live insects, nymphs, or viable eggs (nits) attached within 1 mm of the scalp.
Chemical options consist of FDA‑approved pediculicides such as permethrin 1 % lotion, pyrethrin‑based products, or dimethicone 100 % silicone oil. Apply according to label instructions, ensuring complete coverage of the scalp and hair shaft. Leave the preparation for the recommended duration, then rinse thoroughly. Resistance to permethrin and pyrethrin has been documented; in such cases, dimethicone or benzyl alcohol 5 % lotion provides an alternative with a different mode of action.
Mechanical removal eliminates lice and nits without chemicals. Follow these steps:
« Comb hair with a fine‑toothed lice comb every 3–4 days for two weeks » « Divide hair into sections, pulling each tightly away from the scalp » « Wipe comb teeth on a white paper towel after each pass to verify removal » « Dispose of combed material in sealed plastic bags »
Environmental measures reduce reinfestation risk:
« Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 55 °C) » « Dry items on high heat for at least 30 minutes » « Seal non‑washable items in airtight bags for two weeks » « Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags afterward »
A second treatment session, scheduled 7–10 days after the initial application, addresses any newly hatched lice that survived the first round. Repeat the chosen chemical or mechanical protocol at that time.
Monitoring continues for four weeks. If live lice persist after two treatment cycles, consult a healthcare professional for prescription‑strength options such as malathion 0.5 % or ivermectin 0.5 % lotion, and reassess compliance with the outlined procedures.
