How can I permanently eliminate lice and nits in one day at home? - briefly
Apply a fast‑acting pediculicide (such as 1 % permethrin) to dry hair, leave it for the required duration, then meticulously comb every strand with a fine‑tooth nit comb to extract lice and eggs; repeat the combing after 24 hours while washing all clothing, bedding, and vacuuming the living area.
How can I permanently eliminate lice and nits in one day at home? - in detail
Eliminate head lice and their eggs in a single day at home by following a systematic, thorough approach.
First, confirm infestation. Examine scalp under bright light, part hair in sections, and look for live insects about the size of sesame seeds and tiny, oval, whitish eggs attached close to the scalp. Use a fine-toothed lice comb to separate lice from hair; a live insect caught in the comb confirms the problem.
Second, apply an effective, FDA‑approved pediculicide. Choose a 1% permethrin lotion or a 0.5% malathion solution, following the product’s instructions precisely. Apply to dry hair, saturating strands from scalp to tips, then cover with a plastic cap for the recommended duration (usually 10 minutes). Rinse thoroughly with warm water.
Third, remove remaining nits mechanically. While hair is still damp, run a metal nit comb every 2–3 cm from the scalp outward. After each pass, wipe the comb on a tissue to discard captured eggs. Repeat combing for at least 30 minutes, ensuring no nits remain within 1 mm of the scalp.
Fourth, decontaminate personal items and the environment. Wash all worn clothing, bedding, and towels in hot water (≥ 130 °F/54 °C) and dry on high heat for at least 20 minutes. Seal non‑washable items such as hats, hair accessories, and plush toys in sealed plastic bags for two weeks to starve any surviving lice. Vacuum carpets, upholstery, and vehicle seats, then discard the vacuum bag or clean the canister.
Fifth, prevent re‑infestation. Repeat the combing process 7–10 days after the initial treatment, when any newly hatched lice become mobile. Avoid sharing combs, brushes, hats, or pillows. Encourage all household members to inspect and, if necessary, treat their hair simultaneously.
By executing these steps precisely, live lice are killed, eggs are removed, and the household environment is cleared, achieving permanent eradication within a single day’s effort.
