How and with what can you quickly get rid of lice? - briefly

Apply a 1 % permethrin lotion or a dimethicone‑based product, then remove remaining nits with a fine‑toothed nit comb. Wash all clothing, bedding, and personal items in water above 130 °F (54 °C) and dry on high heat.

How and with what can you quickly get rid of lice? - in detail

Lice infestations develop rapidly; early intervention prevents spread and reduces discomfort. Adult insects survive up to 30 days on a host, laying eggs (nits) that hatch in 7–10 days. Prompt eradication requires killing both live insects and their eggs.

  • Over‑the‑counter insecticides

    • Permethrin 1 % lotion, applied to dry hair for 10 minutes, then rinsed.
    • Pyrethrin‑based shampoos, combined with piperonyl butoxide, used according to label instructions.
      Both agents disrupt nervous system function, killing most adults; a second application after 7 days eliminates newly hatched lice.
  • Prescription options

    • Malathion 0.5 % liquid, left on hair for 8–12 hours before washing.
    • Benzyl alcohol 5 % lotion, applied for 10 minutes, repeated after 7 days.
    • Ivermectin 0.5 % cream, left on scalp for 10 minutes, single dose.
      These products target resistant populations and are effective when over‑the‑counter preparations fail.
  • Mechanical removal

    • Fine‑tooth nit comb, used on wet, conditioned hair, pulling from scalp to tip in systematic sections.
    • Repeating combing every 2–3 days for two weeks removes residual nits and reduces reinfestation risk.
  • Topical silicone (dimethicone)

    • 100 % silicone lotion or spray coats lice, immobilizing them.
    • No neurotoxic chemicals; safe for children over 6 months and pregnant individuals.
    • Apply to dry hair, leave for 8 hours, then shampoo.
  • Adjunctive measures

    • Wash all bedding, clothing, and towels used in the preceding 48 hours in water ≥ 60 °C, then tumble‑dry on high heat.
    • Seal non‑washable items (hats, hair accessories) in sealed plastic bags for 2 weeks.
    • Vacuum carpets and upholstered furniture to remove stray nits.
    • Avoid sharing combs, brushes, hats, or headphones during treatment.
  • Prevention

    • Keep hair tied back in environments with known outbreaks.
    • Conduct regular scalp inspections in schools or daycare settings.
    • Educate caregivers about early signs—itching, visible nits within 1 mm of the scalp—to initiate treatment promptly.

Combining chemical or silicone agents with thorough combing, followed by environmental decontamination, yields the fastest and most reliable clearance of lice. Repeating the chosen regimen after a 7‑day interval addresses hatching cycles and prevents recurrence.
