How can lice be permanently removed from long hair? - in detail
Lice infestations in long hair require a systematic approach that combines thorough inspection, direct removal, targeted treatment, and environmental decontamination.
First, separate the hair into manageable sections using a fine-toothed comb. Begin at the scalp and pull the comb through each strand slowly, wiping the teeth with a disposable tissue after every pass. This mechanical action eliminates adult lice and nits attached to the hair shaft.
Second, apply an FDA‑approved pediculicide that contains either 1 % permethrin or 0.5 % pyrethrin, following the manufacturer’s instructions precisely. Leave the product on the scalp for the recommended duration, then rinse thoroughly.
Third, repeat the chemical treatment after 7–10 days to target any newly hatched nymphs that survived the initial application.
Fourth, maintain a strict cleaning regimen: wash all bedding, towels, and clothing used within the previous 48 hours in hot water (≥ 60 °C) and tumble‑dry on high heat. Items that cannot be laundered should be sealed in a plastic bag for two weeks. Vacuum carpets and upholstered furniture to remove stray eggs.
Fifth, prevent reinfestation by limiting head-to-head contact, avoiding the sharing of combs, hats, or hair accessories, and conducting weekly inspections for at least one month.
A concise protocol:
- Divide hair into 2‑inch sections; comb from scalp outward with a lice‑specific fine comb.
- Apply permethrin 1 % or pyrethrin 0.5 % cream rinse; follow timing guidelines.
- Rinse and repeat treatment after 7–10 days.
- Launder all personal textiles in ≥ 60 °C water; dry on high heat.
- Vacuum and seal non‑washable items for fourteen days.
- Perform weekly scalp checks for four weeks; avoid direct hair contact with others.
Adhering to this multi‑step regimen eliminates the parasite and its eggs, ensuring lasting freedom from infestation in lengthy hair.
