How can lice be eliminated in one day? - in detail
Eliminating head‑lice infestations within 24 hours requires a systematic approach that combines immediate chemical or physical treatment, thorough removal of nits, and environmental decontamination.
First, select an effective pediculicide. Options include:
- 1% permethrin lotion or spray applied to dry hair, left for 10 minutes, then rinsed.
- 0.5% malathion solution, applied for 8–12 minutes under a plastic cap.
- Dimethicone‑based silicone oil, which suffocates insects without resistance issues; leave for 30 minutes before washing.
Apply the chosen product according to label instructions, ensuring complete coverage of scalp and hair shafts. Use a fine‑toothed nit comb immediately after rinsing while hair is still damp; comb from scalp to ends, cleaning the comb after each pass. Repeat combing every 2–3 hours during the day to capture newly hatched nymphs.
Second, address residual eggs. After the initial treatment, repeat the entire process after 7–10 days, when any surviving eggs have hatched, using the same product or a non‑chemical method such as a heated comb (temperature ≥ 50 °C) to destroy remaining nits.
Third, sanitize personal items and surroundings:
- Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 60 °C) and dry on high heat.
- Seal non‑washable items (hats, wigs, hair accessories) in airtight bags for two weeks.
- Vacuum carpets, upholstery, and car seats; discard vacuum bags immediately.
Finally, educate all contacts. Verify that family members and close associates have undergone identical treatment to prevent re‑infestation. Monitoring for at least two weeks with weekly comb checks confirms success. Following these steps can eradicate an active infestation within a single day and sustain a lice‑free environment.
