How can I get rid of lice and nits at home permanently when the hair is long? - briefly
Apply a strong pediculicide or a saturated oil (e.g., olive or tea‑tree) to the scalp, then comb the wet hair with a fine‑toothed nit comb from roots to tips, removing every egg and adult; wash all bedding, clothing, and vacuum the environment. Repeat the treatment after 7–10 days to eliminate any newly emerged lice and prevent reinfestation.
How can I get rid of lice and nits at home permanently when the hair is long? - in detail
Eliminating head‑lice infestations in long hair requires a systematic approach that combines mechanical removal, effective topical treatment, and environmental control.
First, select a suitable pediculicide. Over‑the‑counter options containing 1 % permethrin or 0.5 % pyrethrin are approved for home use. Apply the product according to the label, ensuring the entire scalp and the full length of the hair are saturated. Leave the solution on for the specified time, usually 10 minutes, then rinse thoroughly with lukewarm water.
Second, remove live insects and eggs manually. While the hair is still damp, section it into 2‑inch portions using clips. Use a fine‑toothed lice comb, pulling from the scalp outward with steady pressure. After each pass, wipe the comb on a white tissue to verify removal. Repeat the combing process for each section at least three times, then repeat the entire procedure 7–10 days later to catch any newly hatched nits.
Third, treat the hair after combing. Apply a conditioner or a detangling spray to reduce breakage and make subsequent combing easier. Allow the hair to air‑dry or use a low‑heat setting; high heat can damage the scalp and hair shaft.
Fourth, maintain a clean environment. Wash all clothing, bed linens, and towels used within the previous 48 hours in hot water (≥ 130 °F) and tumble‑dry on high heat. Seal non‑washable items such as hats or stuffed toys in sealed plastic bags for two weeks to starve any remaining lice. Vacuum carpets, upholstery, and car seats thoroughly; discard the vacuum bag or clean the canister afterward.
Fifth, monitor for recurrence. Inspect the scalp and hair daily for the next three weeks. If live insects reappear, repeat the pediculicide treatment and combing regimen after 7 days. Persistent infestations may require a prescription‑strength medication such as 0.5 % malathion or 1 % ivermectin, administered under medical supervision.
By following these steps—approved chemical treatment, rigorous combing, proper hair care, thorough environmental sanitation, and vigilant follow‑up—long hair can be cleared of lice and their eggs permanently without professional intervention.
