How can I quickly get rid of lice on long hair? - briefly
Apply an FDA‑approved 1% permethrin or 0.5% malathion lotion to damp hair, follow the label‑specified exposure time, and rinse thoroughly. Then comb the hair with a fine‑tooth nit comb and repeat both treatment and combing after 7–10 days to eliminate any remaining eggs.
How can I quickly get rid of lice on long hair? - in detail
Dealing with a head‑lice infestation in long hair requires a systematic approach that combines chemical or natural treatment, thorough combing, and environmental sanitation.
First, confirm the presence of lice by parting the hair in sections and examining the scalp for live insects or nits attached close to the hair shaft. Use a bright light and a magnifying lens if available.
Choose a treatment method:
- Over‑the‑counter pediculicides (permethrin 1 % or pyrethrin with a piperonyl‑butoxide booster). Apply according to the label, covering the entire length of the hair from scalp to tips. Leave the product on for the specified time, then rinse thoroughly.
- Prescription options (malathion 1 % or ivermectin lotion). These are reserved for resistant infestations; a medical professional must prescribe them.
- Non‑chemical alternatives such as dimethicone‑based lotions, tea‑tree oil mixtures, or a heated oil treatment. Apply uniformly, heat the scalp gently (not above 45 °C) to immobilize the insects, then rinse.
After the active ingredient has been applied, follow these combing steps:
- While the scalp is still damp, use a fine‑toothed nit comb (0.2 mm spacing). Start at the scalp, pull the comb through each strand to the ends.
- Work in 1‑inch sections, repeating the process three times per section.
- Rinse the comb after each pass to remove captured lice and nits.
- Continue combing for at least 30 minutes, then repeat the entire combing session after 7–10 days to catch any newly hatched lice.
Clean personal items and the surrounding environment:
- Wash all clothing, bedding, and towels used within the past 48 hours in hot water (≥ 60 °C) and dry on the highest heat setting.
- Seal non‑washable items (hats, hair accessories) in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard the vacuum bag or clean the canister afterward.
- Soak combs, brushes, and hair clips in hot water (≥ 50 °C) for 10 minutes or immerse them in rubbing alcohol.
Monitor the scalp daily for at least three weeks. If live lice reappear after the second treatment, repeat the chemical or natural regimen and combing process. Persistent infestations may require a dermatologist’s evaluation for alternative therapies.
