What should be done to remove lice? - briefly
Apply an FDA‑approved pediculicide such as 1 % permethrin or a pyrethrin‑based lotion, following the product’s recommended contact time. After rinsing, comb the hair while wet with a fine‑tooth nit comb to extract any remaining nits, and repeat the treatment in 7–10 days to ensure all hatchlings are eliminated.
What should be done to remove lice? - in detail
Lice infestations require a systematic approach that combines direct treatment, environmental sanitation, and ongoing monitoring.
The first step is to confirm the presence of live insects or viable nits attached within ¼ inch of the scalp. Use a fine‑toothed comb on damp hair, examining the comb after each pass for moving lice or intact eggs.
Once confirmed, apply an approved pediculicide according to the product label. Options include:
- Over‑the‑counter shampoos or lotions containing 1 % permethrin or 0.5 % pyrethrins with piperonyl butoxide. Apply to dry hair, leave for the specified time, then rinse thoroughly.
- Prescription‑only agents such as 0.5 % ivermectin lotion or 0.05 % malathion. Use when resistance to OTC formulas is suspected or after repeated treatment failures.
After the initial application, repeat the treatment after 7–9 days to eliminate newly hatched nits that survived the first dose.
Mechanical removal complements chemical treatment. Perform a thorough combing session with a nit comb every 2–3 days for two weeks. Divide hair into sections, pull the comb from scalp to tip, and wipe the teeth after each pass. Dispose of collected material in sealed bags.
Environmental control reduces re‑infestation risk:
- Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 130 °F) and dry on high heat.
- Seal non‑washable items in plastic bags for two weeks.
- Vacuum carpets, upholstery, and vehicle seats; discard vacuum bags immediately.
- Avoid sharing combs, hats, or hair accessories during treatment.
Monitor all household members for at least three weeks. If any person shows signs of infestation, repeat the treatment protocol without delay.
Document the dates of each application and combing session to ensure adherence to the schedule. Adjust the regimen if resistance is suspected, consulting a healthcare professional for alternative therapies such as oral ivermectin or dimeticone‑based products.
By integrating chemical agents, precise mechanical removal, and strict environmental hygiene, complete eradication of lice can be achieved efficiently.
