How can lice be quickly and effectively removed from a person? - briefly
Apply a pediculicide shampoo, then comb wet, conditioned hair with a fine‑toothed lice comb, removing nits; repeat the process after 7–10 days to eradicate newly hatched insects. Wash bedding, clothing, and personal items in hot water and dry on high heat to prevent reinfestation.
How can lice be quickly and effectively removed from a person? - in detail
Effective eradication of head lice requires a coordinated approach that combines chemical treatment, mechanical removal, and environmental control.
A pediculicide containing 1 % permethrin or 0.5 % malathion applied to dry hair and left for the recommended duration eliminates the majority of live insects. After the exposure period, rinse thoroughly with lukewarm water.
Mechanical extraction enhances results. Use a fine‑toothed nit comb, preferably metal, and follow these steps:
- Section hair into 1‑inch sections.
- Run the comb from scalp to tip in a single, steady stroke.
- Rinse the comb in a container of hot water after each pass to prevent re‑infestation.
- Repeat the process for each section, then repeat the entire combing session after 7–10 days to capture newly hatched nymphs.
Environmental measures reduce reinfestation risk.
- Wash all bedding, hats, and clothing worn within the previous 48 hours in water ≥ 60 °C, then dry on high heat.
- Seal non‑washable items in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags immediately.
For resistant cases, prescription‑strength agents such as ivermectin lotion (0.5 %) or oral ivermectin (200 µg/kg) may be employed under medical supervision.
Monitoring continues for four weeks. Inspect hair every 2–3 days using a bright light and the nit comb; document the presence of live lice or viable eggs. Absence of findings over this period confirms successful elimination.
