How to remove lice and nits from long hair? - briefly
Use a fine-toothed nit comb on wet, conditioned hair after applying a pediculicide shampoo, combing from scalp to tip in sections and repeating every 2–3 days for two weeks. Dispose of combed lice and nits, launder clothing and bedding in hot water, and keep hair trimmed to minimize re‑infestation.
How to remove lice and nits from long hair? - in detail
Effective removal of head‑lice infestations in long hair requires a systematic approach that combines mechanical extraction, chemical treatment, and thorough cleaning of the environment.
Begin by selecting a fine‑toothed lice comb made of metal or high‑quality plastic. Comb the hair while it is damp but not saturated; apply a conditioner or a specialized detangling spray to reduce tangling and allow the teeth to glide through the strands. Starting at the scalp, pull the comb forward in short, deliberate strokes, then reverse the motion to lift eggs (nits) from the shaft. After each pass, wipe the comb on a white tissue or rinse it in hot water to inspect for captured insects. Repeat the process every 2–3 days for at least two weeks, because newly hatched nits require several days to mature.
If a pediculicide is preferred, choose a product approved by health authorities that contains either dimethicone, pyrethrin, or a non‑neurotoxic silicone‑based formula. Follow the label precisely: apply the lotion or shampoo to dry hair, massage to the roots, leave for the recommended exposure time, then rinse thoroughly. A second application after 7–10 days eliminates any survivors that emerged after the first treatment. Avoid products with excessive alcohol or harsh chemicals, as they can damage fragile hair shafts.
Supplement the combing and chemical steps with these supportive measures:
- Wash all bedding, towels, and clothing used within the previous 48 hours in hot water (≥60 °C) and dry on high heat.
- Seal non‑washable items (e.g., stuffed toys) in airtight bags for two weeks to starve any remaining lice.
- Vacuum carpets, upholstered furniture, and car seats to remove stray insects.
- Do not share combs, hats, or hair accessories until the infestation is cleared.
For individuals with sensitive scalps or allergic reactions, a non‑chemical option involves repeated wet‑combing alone. Wet the hair with a mixture of water and a small amount of olive oil, then follow the same combing routine described earlier. This method may require more frequent sessions but eliminates exposure to insecticides.
After successful eradication, maintain a preventive routine: schedule a weekly combing session, keep hair clean and well‑conditioned, and avoid direct head contact with known carriers. Consistent monitoring for a month post‑treatment ensures that any resurgence is detected early and addressed promptly.
