What can be used to remove lice and nits from long hair? - briefly
A fine‑toothed nit comb used after applying a lice‑killing product such as a 1 % permethrin shampoo or a dimethicone‑based treatment effectively eliminates both insects and their eggs in long hair. Repeating the combing process every 2–3 days for two weeks ensures complete removal.
What can be used to remove lice and nits from long hair? - in detail
Effective removal of head‑lice and their eggs from long hair requires a combination of chemical, mechanical, and environmental strategies.
A proven chemical approach uses a 1 % permethrin lotion or a 0.5 % malathion solution applied according to the manufacturer’s instructions. Both agents penetrate the hair shaft and kill live insects within minutes. For individuals allergic to synthetic insecticides, a 10 % dimethicone oil or a 0.5 % benzyl alcohol spray provides a non‑neurotoxic alternative that suffocates lice and loosens nits.
Mechanical removal is essential because eggs adhere tightly to the hair shaft. A fine‑toothed nit comb, preferably with teeth spaced 0.2 mm apart, should be used on wet, conditioned hair. The procedure is:
- Apply a detangling conditioner to reduce friction.
- Section the hair into 2–3 cm strands.
- Comb from scalp outward, rinsing the comb after each pass.
- Repeat the entire process every 2–3 days for at least two weeks.
Adjunctive measures improve success rates:
- Wash all bedding, hats, and personal items in water ≥ 60 °C or seal them in a plastic bag for 14 days.
- Vacuum carpets and upholstered furniture to eliminate stray insects.
- Avoid sharing combs, brushes, or hair accessories during treatment.
When chemical resistance is suspected, a combination therapy—using a dimethicone product followed by thorough nit‑combing—offers the highest eradication probability. Continuous monitoring, with visual inspection of the scalp and hair, confirms complete clearance.
