How can lice be eliminated in one go? - briefly
Use a single application of an FDA‑approved pediculicide (e.g., 1 % permethrin or dimethicone) combined with thorough nit removal using a fine‑toothed lice comb. Perform a second combing session 7–10 days later to capture any hatchlings.
How can lice be eliminated in one go? - in detail
Effective eradication of head‑lice requires a systematic approach that combines immediate treatment, thorough removal of nits, and environmental decontamination. The goal is to achieve complete elimination in a single intervention cycle.
The first step is to select an appropriate pediculicide. FDA‑approved options include:
- 1% permethrin lotion or shampoo, applied to dry hair, left for 10 minutes, then rinsed.
- 0.5% malathion lotion, applied to damp hair, left for 8–12 hours, then washed off.
- Dimethicone‑based products, which suffocate insects without neurotoxic action; apply to saturated hair, leave for 30 minutes, rinse thoroughly.
Apply the chosen product according to the manufacturer’s instructions, ensuring complete coverage from scalp to hair tips. Use a fine‑toothed lice comb immediately after rinsing to extract live insects and eggs. Run the comb through each section of hair at least five times, wiping the teeth with a disposable cloth after each pass.
After the initial combing, repeat the process after 7–10 days. This interval corresponds to the hatching period of any remaining nits, preventing reinfestation.
Environmental control includes:
- Washing all bedding, towels, and clothing worn within the previous 48 hours in hot water (≥ 60 °C) and drying on high heat for at least 30 minutes.
- Sealing non‑washable items (e.g., hats, hair accessories) in a sealed plastic bag for two weeks.
- Vacuuming carpets, upholstery, and vehicle seats to remove stray lice or eggs.
Avoid re‑infestation by discouraging head‑to‑head contact and sharing of personal items. Regular inspection of hair, performed twice weekly for three weeks, confirms the success of the single‑treatment protocol.
