How can you get rid of lice and nits? - in detail
Eliminate head‑lice infestations by combining immediate treatment, thorough cleaning, and preventive measures.
Begin with a medicated shampoo or lotion containing 1 % permethrin, 0.5 % pyrethrin, or a prescription‑strength agent such as malathion or ivermectin. Apply according to the product instructions, leave on the scalp for the specified time, then rinse thoroughly.
After the chemical treatment, remove remaining insects and eggs with a fine‑toothed nit comb. Work in sections, combing from the scalp outward, wiping the comb after each pass. Repeat the combing process every 2–3 days for two weeks to capture any newly hatched nymphs.
If resistance to over‑the‑counter agents is suspected, switch to a prescription option or use a non‑chemical method such as a heated air device that blows air at 130 °F (54 °C) for several minutes per section of hair.
Simultaneously, decontaminate personal items and the environment:
- Wash clothing, bedding, and towels used within the past 48 hours in hot water (≥130 °F) and dry on high heat for at least 20 minutes.
- Seal non‑washable items in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstery, and car seats; discard the vacuum bag or clean the canister afterward.
Avoid re‑infestation by implementing these habits:
- Instruct all household members to check hair daily for live insects or eggs.
- Restrict head‑to‑head contact during play and sports.
- Do not share combs, hats, hair accessories, or pillows.
- Encourage regular hair washing with a mild shampoo to maintain scalp hygiene.
If symptoms persist after two weeks of treatment and combing, consult a healthcare professional for alternative therapies or laboratory confirmation. Continuous monitoring for at least one month ensures complete eradication.
