How to remove lice if they do not come out? - briefly
Apply a pediculicide (e.g., permethrin or dimethicone) according to the label, then meticulously comb wet hair with a fine-tooth nit comb to extract remaining nits, repeating the process after 7‑10 days to catch any hatchlings. If lice persist, consult a healthcare professional for stronger prescription options or alternative treatments.
How to remove lice if they do not come out? - in detail
Lice that remain after initial treatment require a systematic approach that combines thorough combing, targeted medicaments, and environmental sanitation.
First, inspect the scalp with a fine‑toothed nit‑comb under bright light. Separate sections of hair and pull the comb from the scalp to the tip, wiping each pass on a white tissue. Continue until no live insects are seen for several minutes. Repeat this process daily for at least one week, because newly hatched nits emerge within 7‑10 days.
Second, apply an approved pediculicide that contains either 1 % permethrin, 0.5 % malathion, or a dimethicone‑based lotion. Follow the manufacturer’s instructions precisely: apply to dry hair, leave for the recommended duration, then rinse thoroughly. A second application after 7–10 days eliminates any lice that survived the first exposure.
Third, consider non‑chemical options when resistance is suspected. Dimethicone oil coats the insect’s exoskeleton, causing asphyxiation without toxicity. Apply a generous amount, cover the scalp with a shower cap for 8–10 hours, then rinse and comb out the dead insects.
Fourth, decontaminate personal items. Wash bedding, clothing, and towels in hot water (≥ 130 °F) for at least 30 minutes; dry on high heat. Seal non‑washable items in a sealed plastic bag for two weeks, as lice cannot survive beyond this period without a host.
Fifth, treat the environment. Vacuum carpets, upholstered furniture, and car seats; discard the vacuum bag or clean the canister afterward. Use a household spray containing 0.5 % permethrin on surfaces that cannot be laundered, following safety guidelines.
Finally, monitor for reinfestation. Perform weekly comb checks for four weeks after treatment. If live lice reappear, repeat the medicated treatment and reassess compliance with the combing schedule and environmental measures.
By integrating meticulous mechanical removal, appropriate chemical or silicone‑based agents, and rigorous cleaning of surroundings, persistent infestations can be eradicated.
