How to eliminate lice? - briefly
Apply a permethrin‑ or pyrethrin‑based shampoo or lotion as directed, leave it on for the recommended duration, then remove remaining nits with a fine‑toothed comb. Repeat the treatment after 7–10 days and launder bedding, clothing, and personal items in hot water.
How to eliminate lice? - in detail
Eliminating head‑lice infestations requires a systematic approach that combines chemical treatment, mechanical removal, environmental sanitation, and preventive measures.
First, select an appropriate pediculicide. Over‑the‑counter options include permethrin 1 % lotion or pyrethrin‑based products. Apply according to the label: distribute the product through damp hair, leave for the recommended time (usually 10 minutes), then rinse thoroughly. For resistant cases, consider a prescription‑only agent such as malathion 0.5 % or ivermectin lotion, applied as directed by a healthcare professional.
Second, remove live insects and eggs (nits) manually. Use a fine‑toothed lice comb on wet, conditioned hair. Section the hair and comb from scalp to tip, wiping the comb after each pass. Repeat the process every 2–3 days for two weeks to capture newly hatched nymphs. A second combing session after seven days helps ensure complete eradication.
Third, treat personal items and surroundings. Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 130 °F/54 °C) and dry on high heat for at least 20 minutes. Items that cannot be laundered should be sealed in a plastic bag for two weeks or placed in a freezer at –4 °F (–20 °C) for 24 hours. Vacuum carpets, upholstered furniture, and car seats to remove stray lice and nits.
Fourth, implement preventive strategies. Advise regular head‑checking, especially after contact with schools or camps. Avoid sharing combs, hats, helmets, or hair accessories. Encourage the use of personal hair coverings in high‑risk settings.
A concise protocol:
- Apply a suitable lice‑killing lotion or shampoo; follow timing instructions precisely.
- Comb hair with a nit‑comb every 2–3 days for 14 days.
- Launder or isolate all recent clothing and bedding.
- Clean living areas with vacuuming and heat treatment.
- Educate all household members on avoidance of head‑to‑head contact and personal item sharing.
Adhering to these steps eliminates active lice populations and prevents re‑infestation. If symptoms persist after two treatment cycles, consult a medical professional for alternative therapies or underlying conditions.
