We have lice, what should we do? - in detail
Lice infestation requires immediate identification, treatment, and preventive measures.
First, confirm the presence of live insects or nits attached to hair shafts. Examine the scalp under bright light, using a fine-toothed comb to separate strands and reveal any eggs.
Second, select an appropriate pediculicide. Options include:
- Permethrin 1% lotion applied to dry hair, left for ten minutes before rinsing.
- Dimethicone‑based products that suffocate insects without resistance issues.
- Malathion 0.5% liquid for resistant cases, applied for eight hours.
Follow the manufacturer’s instructions precisely; incorrect use can reduce efficacy and increase irritation.
Third, remove residual nits mechanically. After treatment, comb wet hair with a fine-tooth nit comb, working from scalp outward. Repeat combing every 2–3 days for two weeks to capture any newly hatched lice.
Fourth, decontaminate personal items and environment. Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥60 °C) and dry on high heat. Items that cannot be laundered should be sealed in a plastic bag for at least two weeks. Vacuum carpets and upholstered furniture to eliminate stray insects.
Fifth, educate all household members. Inform them of transmission routes—direct head‑to‑head contact and shared personal items—and advise against sharing combs, hats, or headphones.
Finally, schedule a follow‑up inspection after seven days. If live lice persist, repeat the chemical treatment with a different active ingredient, or consult a healthcare professional for prescription options. Continuous monitoring for at least four weeks reduces the risk of re‑infestation.
