How can I remove lice and nits in a single treatment? - briefly
Apply a 1 % permethrin or pyrethrin shampoo, then immediately comb out all nits with a fine‑tooth nit comb; repeat the treatment after 7–10 days to eliminate any newly emerged lice. This single‑session protocol eradicates both adult insects and their eggs.
How can I remove lice and nits in a single treatment? - in detail
Effective eradication of head lice and their eggs in a single session requires a combination of chemical or physical agents, thorough mechanical removal, and proper post‑treatment care.
Begin with a proven pediculicide that also possesses ovicidal activity. Products containing 1% permethrin, 0.5% malathion, or dimethicone‑based formulas are documented to kill both live insects and unhatched eggs when applied according to manufacturer instructions. Apply the solution to dry hair, saturating the scalp and strands from root to tip. Leave the product on for the specified duration, typically 10–15 minutes, then rinse thoroughly with warm water.
Immediately after rinsing, use a fine‑toothed nit comb (spacing ≤0.2 mm) on wet, conditioned hair. Section the hair into 1‑inch sections and comb from scalp outward, wiping the comb after each pass. Continue until no visible nits or lice are detected. This mechanical step eliminates any surviving eggs that the chemical may have missed.
Dispose of all combed material, towels, and clothing used during treatment by sealing them in a plastic bag for 48 hours or washing at ≥60 °C. Vacuum carpets, upholstery, and vehicle seats to remove stray insects.
A single follow‑up inspection 7–10 days later confirms complete clearance. If any live lice are observed, repeat the entire process with the same product, ensuring the same thorough combing. Consistent adherence to these steps eliminates infestation without the need for multiple treatment cycles.
