How to get rid of lice and nits? - briefly

Apply an FDA‑approved lice treatment to the hair, follow the recommended exposure time, then remove all eggs with a fine‑toothed nit comb; wash bedding, clothing, and personal items in hot water and repeat the treatment after 7–10 days to eliminate any newly hatched insects.

How to get rid of lice and nits? - in detail

Lice infestations require a systematic approach that combines immediate eradication, thorough cleaning of personal items, and ongoing monitoring.

First, confirm the presence of live insects and their oval-shaped eggs attached to hair shafts close to the scalp. Use a fine-toothed comb on damp hair to separate strands and expose any hidden specimens.

Next, select an appropriate treatment method:

  1. Over‑the‑counter pediculicides – shampoos or lotions containing 1 % permethrin or 0.5 % pyrethrin. Apply according to the product label, leave for the recommended duration, then rinse thoroughly. A second application 7–10 days later eliminates newly hatched nymphs.
  2. Prescription options – malathion 0.5 % lotion, ivermectin oral tablets, or benzyl alcohol lotion for resistant cases. These require a healthcare professional’s authorization and adherence to dosage instructions.
  3. Manual removal – after chemical treatment, comb hair with a metal nit comb at 2‑mm intervals, starting at the scalp and moving toward the ends. Perform this process every 2‑3 days for two weeks, ensuring all eggs are extracted.
  4. Alternative agents – dimethicone‑based products suffocate insects without neurotoxic effects. Apply liberally, cover with a plastic cap for 10 minutes, then rinse.

Simultaneously, decontaminate the environment:

  • Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 60 °C) and dry on high heat.
  • Seal non‑washable items in sealed plastic bags for two weeks.
  • Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags immediately.

Prevent re‑infestation by:

  • Advising all close contacts to undergo simultaneous treatment.
  • Avoiding head‑to‑head contact and sharing of combs, hats, or headphones.
  • Conducting weekly inspections for at least one month after treatment.

If live insects persist after two treatment cycles, consult a medical professional for alternative regimens or resistance testing. Continuous documentation of treatment dates and outcomes supports effective resolution and reduces the likelihood of recurrence.
