How should lice nits be treated? - briefly
Apply a licensed pediculicide or steam‑based treatment, then use a fine‑tooth nit comb to remove every attached egg. Launder bedding and clothing at 130 °F and repeat the process after 7–10 days to eradicate any newly hatched lice.
How should lice nits be treated? - in detail
Treating lice eggs requires a combination of mechanical removal, chemical agents, and environmental control.
First, use a fine-toothed nit comb on damp hair. Section the scalp, apply a conditioner to reduce friction, and pull the comb from the scalp outward. After each pass, wipe the comb on a paper towel and repeat until no visible nits remain. This process should be performed every 2–3 days for at least two weeks to catch newly hatched insects.
Second, apply an approved pediculicide that contains either 1 % permethrin, 0.5 % pyrethrin with piperonyl butoxide, or 0.05 % malathion. Follow the manufacturer’s instructions precisely: apply to dry hair, leave for the recommended duration, then rinse thoroughly. A second application 7–10 days later eliminates any lice that survived the first dose.
Third, consider a dimethicone‑based product. Dimethicone suffocates both lice and nits without neurotoxic effects. Apply to dry hair, cover with a shower cap for the specified time, then rinse. No repeat treatment is typically required, but combing remains essential to remove residual eggs.
Fourth, decontaminate personal items. Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 60 °C) and dry on high heat. Seal non‑washable items in a sealed plastic bag for two weeks to prevent hatching.
Fifth, limit re‑infestation risk. Avoid sharing combs, hats, or hair accessories. Vacuum carpets and upholstered furniture, and clean hairbrushes by soaking them in hot water for 10 minutes.
Finally, monitor the situation. Examine the scalp daily for live lice or new nits. If live insects persist after two treatment cycles, consult a healthcare professional for prescription‑strength options such as ivermectin lotion or oral therapy.
By integrating meticulous combing, appropriate topical agents, and thorough environmental hygiene, the eradication of lice eggs can be achieved reliably.
