How can one cure lice? - briefly
Apply a licensed pediculicide such as permethrin 1 % or pyrethrin, following label instructions, then comb hair with a fine‑toothed lice comb to remove nits; repeat the treatment after 7–10 days to eradicate newly hatched insects. Wash clothing, bedding, and personal items in hot water or seal them in a plastic bag for two weeks to prevent re‑infestation.
How can one cure lice? - in detail
Lice infestations require prompt eradication to prevent prolonged discomfort and transmission. Effective treatment combines direct scalp therapy, thorough removal of nits, and environmental decontamination.
- Over‑the‑counter pediculicides contain permethrin (1 %) or pyrethrin with piperonyl‑butoxide. Apply to dry hair, leave for the manufacturer‑specified duration (usually 10 minutes), rinse, and repeat after 7–10 days to eliminate newly hatched lice. Follow label instructions regarding age limits and contraindications.
- Prescription options include malathion (0.5 %), benzyl alcohol lotion (5 %), and ivermectin (0.5 %). These agents are reserved for resistant cases or when OTC products fail. Obtain medical supervision to assess safety, especially for children under two years and pregnant individuals.
Non‑chemical approaches complement pharmacologic measures.
- Wet combing involves saturating hair with conditioner, then using a fine‑toothed lice comb at 2‑inch intervals from scalp to tip. Perform the process every 2–3 days for two weeks, discarding each combed strand to prevent re‑infestation.
- Manual removal of nits with fine tweezers can reduce the need for repeated chemical exposure. Conduct under adequate lighting, pulling each egg from the hair shaft without breaking the shell.
Environmental control limits reinfestation.
- Wash all bedding, clothing, and towels used within the previous 48 hours in hot water (≥ 60 °C) and dry on high heat. Items that cannot be laundered should be sealed in plastic bags for two weeks.
- Vacuum carpets, upholstered furniture, and vehicle seats to remove stray hairs containing nits. Avoid sharing combs, hats, or hair accessories during treatment.
Monitoring continues after initial therapy.
