What should be done when there are lice? - in detail
When an infestation of head lice is confirmed, immediate action focuses on eradication, prevention of re‑infestation, and environmental decontamination.
The primary treatment consists of applying a pediculicidal product approved by health authorities. Follow the manufacturer’s instructions precisely: apply the lotion or shampoo to dry hair, leave it on for the recommended duration, then rinse thoroughly. Repeat the application after seven to ten days to target newly hatched nymphs that survived the first treatment.
Mechanical removal complements chemical treatment. Use a fine‑toothed lice comb on wet, conditioned hair, starting at the scalp and moving toward the ends. Perform combing in sections, repeating the process for at least ten minutes per session. Conduct combing sessions every two days for two weeks to ensure complete elimination.
Personal hygiene measures reduce the risk of recurrence. Wash all clothing, bedding, and towels used within the previous 48 hours in hot water (minimum 130 °F/54 °C) and tumble‑dry on high heat. Items that cannot be laundered should be sealed in a plastic bag for two weeks, depriving lice of a viable habitat.
Close contacts require examination. Inspect family members and close acquaintances promptly; treat any additional cases with the same regimen to prevent cross‑contamination.
Environmental cleaning should address items that may harbor lice eggs. Vacuum carpets, upholstered furniture, and vehicle seats thoroughly. Discard or isolate personal items such as hairbrushes, combs, hats, and hair accessories; clean them with hot water or replace them if necessary.
Education reinforces long‑term control. Inform caregivers and affected individuals about the life cycle of lice, the importance of completing the full treatment schedule, and strategies for early detection, such as regular scalp inspections.
By combining chemical treatment, meticulous combing, thorough laundering, contact screening, and environmental sanitation, the infestation can be resolved efficiently and the likelihood of recurrence minimized.
