What to do after discovering lice? - in detail
Discovering head‑lice requires swift, systematic action to eliminate the infestation and prevent re‑contamination.
First, isolate the affected individual. Keep them away from close contact with others until treatment begins.
Second, apply an approved pediculicide. Follow the product label precisely: apply the lotion or shampoo to dry hair, cover the scalp for the recommended time, then rinse thoroughly. For resistant cases, a second application after seven to ten days is essential, as newly hatched nymphs may survive the initial dose.
Third, remove live insects and eggs manually. Use a fine‑toothed comb, pulling the hair taut and sliding the comb from scalp to ends in small sections. Rinse the comb in hot water after each pass. Repeat the combing process at least once daily for ten days.
Fourth, decontaminate personal items. 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 in a sealed plastic bag for two weeks to starve any remaining lice.
Fifth, treat the environment. Vacuum carpets, upholstered furniture, and car seats. Discard hair accessories, brushes, and combs, or soak them in hot water for ten minutes.
Sixth, monitor for recurrence. Inspect the scalp and hair of the treated person and close contacts every two days for two weeks. If live lice reappear, repeat the chemical treatment and combing regimen.
Seventh, implement preventive measures. Encourage regular head checks, especially after group activities. Advise against sharing hats, hair ties, or headphones. Maintain short hair where feasible, and educate caregivers on early detection.
By adhering to this sequence—containment, chemical treatment, meticulous combing, thorough laundering, environmental sanitation, ongoing surveillance, and preventive habits—the infestation can be eradicated efficiently and sustainably.
