How can lice nits be combated? - briefly
Removal requires thorough wet combing with a fine‑toothed nit comb after applying a conditioning or oily treatment to loosen the egg shells. Follow with an approved pediculicide shampoo and repeat the process after 7–10 days to eliminate any newly hatched lice.
How can lice nits be combated? - in detail
Effective elimination of lice eggs requires a combination of mechanical removal, chemical agents, and environmental sanitation.
Mechanical removal relies on a fine-toothed nit comb. The comb must be used on wet, conditioned hair to reduce breakage. Each pass should start at the scalp and move outward, repeating until no live lice or viable eggs are visible. Comb through the entire head at least once daily for ten days, because newly hatched lice become mobile after about 24 hours.
Chemical agents include over‑the‑counter shampoos and lotions containing permethrin, pyrethrin, or dimethicone. Apply according to the product label, leave the solution on the scalp for the specified time, then rinse thoroughly. For resistant infestations, a prescription‑only medication such as ivermectin may be required; a healthcare professional should oversee its use.
Environmental sanitation reduces the risk of re‑infestation. Wash bedding, clothing, and personal items used within the previous 48 hours in hot water (≥ 130 °F) and dry on high heat for at least 30 minutes. Items that cannot be laundered should be sealed in a plastic bag for two weeks, the typical survival period for lice eggs. Vacuum carpets, upholstery, and vehicle seats to remove detached nits.
Preventive measures complement treatment. Encourage regular hair inspections, especially in group settings such as schools. Avoid sharing combs, hats, or hair accessories. Maintain short hair lengths where feasible, as longer hair provides more surface area for egg attachment.
Step‑by‑step protocol
- Prepare hair – Wet and apply a conditioner to facilitate combing.
- Comb – Use a nit comb, working from scalp outward; repeat for the entire head.
- Treat – Apply a suitable pediculicide, following timing instructions precisely.
- Rinse – Remove product thoroughly; repeat combing after the recommended interval (usually 7–10 days).
- Sanitize – Launder or isolate personal items; vacuum surroundings.
- Monitor – Continue daily inspections for two weeks; repeat treatment if live lice reappear.
Adhering to this integrated approach maximizes the likelihood of eradicating lice eggs and preventing recurrence.
