Long hair: how can you permanently get rid of lice and nits in one day? - briefly
Apply a 1 % permethrin (or pyrethrin) shampoo, leave it on for the recommended duration, then comb the hair with a fine‑tooth nit comb to remove all eggs. Wash all clothing, bedding, and accessories in water ≥ 130 °F and seal any non‑washable items in airtight containers for 48 hours to prevent re‑infestation.
Long hair: how can you permanently get rid of lice and nits in one day? - in detail
Eliminating head‑lice infestations from long hair in a single day requires a combination of chemical treatment, meticulous combing, and immediate environmental control.
Apply a proven pediculicide (e.g., 1 % permethrin lotion or 0.5 % malathion solution) to thoroughly saturated hair. Follow the product’s instructions for exposure time, typically 10 minutes, then rinse with warm water. Ensure the scalp and hair shaft are completely covered, especially the lower layers where nits attach.
While the hair remains damp, use a fine‑toothed nit comb (0.2 mm spacing). Divide the hair into sections of 1–2 inches, start at the scalp, and pull the comb straight through to the ends. After each pass, wipe the comb on a paper towel and re‑wet any dry strands. Repeat the process until no live insects or viable eggs are visible.
If any nits remain, repeat the combing cycle after a second application of the pediculicide, as recommended by the manufacturer (usually 7–9 days later). This second treatment targets any eggs that hatched after the first exposure.
To prevent re‑infestation, wash all personal items (pillows, hats, hairbrushes, combs) in hot water (≥ 60 °C) or seal them in a plastic bag for two weeks. Vacuum carpets and upholstery, and avoid sharing hair accessories.
Finally, schedule a follow‑up inspection 24 hours after the initial treatment. Confirm the absence of live lice and empty nits. If any are detected, repeat the chemical and combing protocol immediately. Consistent execution of these steps eliminates the infestation permanently within one day and minimizes the risk of recurrence.
