How to remove lice and nits in a single treatment? - briefly
Use a 1% permethrin or dimethicone lice treatment, leave it on the scalp for the recommended time, then immediately run a fine‑toothed nit comb through the damp hair to extract all eggs; repeat the combing after 7–10 days to catch any newly hatched nymphs. This single‑session protocol eradicates both live insects and their ova.
How to remove lice and nits in a single treatment? - in detail
Effective eradication of head‑lice and their eggs in a single session requires a systematic approach that combines chemical or physical treatment with meticulous mechanical removal.
Begin by separating the hair into manageable sections. Apply a verified lice‑killing product—such as a 1% permethrin lotion, a 0.5% malathion solution, or a dimethicone‑based silicone oil—according to the manufacturer’s instructions. Ensure the scalp and hair are fully saturated; the product must remain wet for the prescribed exposure time, typically 10–15 minutes.
While the agent is active, use a fine‑toothed, metal lice comb. Starting at the scalp, draw the comb through each section from root to tip in a slow, steady motion. After each pass, wipe the comb on a clean tissue and repeat until no live insects or viable eggs are visible. Perform this combing step at least twice during the exposure period to capture newly hatched nymphs.
Rinse the hair thoroughly with warm water, removing all residual product. Follow with a gentle conditioner to reduce hair breakage and to facilitate a final combing pass. Dry the scalp completely; moisture encourages re‑infestation.
After treatment, wash all personal items that may harbor lice—pillowcases, hats, brushes, combs, and hair accessories—using hot water (≥ 60 °C) or sealing them in a plastic bag for two weeks. Vacuum upholstered furniture and carpets to eliminate stray nits.
Maintain vigilance for the next 7–10 days. Conduct daily inspections with a lice comb, focusing on the nape and behind the ears. If any live lice are detected, repeat the combing procedure immediately; a second chemical application is unnecessary if the initial protocol was followed precisely.
By adhering to this protocol—proper product application, thorough combing, and strict post‑treatment hygiene—complete elimination of both lice and their eggs can be achieved in one treatment session.
