How to cure lice and nits in one go? - briefly

Apply an FDA‑approved pediculicide formulated to eradicate both live lice and their eggs, then follow the product’s instructions and comb the hair with a fine-toothed nit comb while wet to eliminate any remaining nits.

How to cure lice and nits in one go? - in detail

Lice infestations require simultaneous eradication of adult insects and their eggs. Begin with a thorough inspection: separate hair into sections, use a fine-toothed nit comb under bright light, and confirm presence of live lice and viable nits within 1 cm of the scalp.

Choose a treatment that attacks both stages. Options include:

  • Permethrin 1 % lotion – applied to dry hair, left for 10 minutes, then rinsed. Effective against live lice; resistant eggs may survive.
  • Pyrethrin‑based sprays – combined with piperonyl‑butoxide to enhance penetration; repeat after 7 days to target hatching nits.
  • Spinosad 0.9 % suspension – kills lice and most nits on first application; no second treatment required in most cases.
  • Ivermectin oral tablets – 200 µg/kg single dose for resistant infestations; follow with a nit‑comb session after 24 hours.

Regardless of product, follow these precise steps:

  1. Apply medication exactly as directed, covering the entire scalp and hair length.
  2. Leave the preparation for the specified time; do not rinse prematurely.
  3. Rinse thoroughly with warm water; avoid shaving or using harsh shampoos that could dilute the active ingredient.
  4. Comb out all visible nits with a nit comb while hair is still damp; repeat combing every 2–3 days for two weeks.
  5. Schedule a second application (if required) 7–10 days after the first to eliminate newly hatched lice.

Environmental control complements chemical treatment:

  • Wash all bedding, clothing, and towels used within the previous 48 hours in water ≥ 60 °C, then tumble‑dry on high heat.
  • Seal non‑washable items (e.g., stuffed toys) in airtight bags for two weeks.
  • Vacuum carpets, upholstered furniture, and vehicle seats; discard vacuum bags immediately.
  • Avoid sharing combs, hats, or hair accessories until the infestation is cleared.

Monitor progress by inspecting the scalp daily for live lice. Absence of live insects after 14 days indicates successful eradication. If live lice persist, repeat the entire protocol using a different active ingredient to overcome potential resistance.
