If lice appear, how can they be eliminated? - briefly
Treat the infestation with a pediculicide shampoo or lotion, such as permethrin or dimethicone, and remove remaining nits using a fine‑toothed comb. Repeat the treatment after 7–10 days and wash all bedding and clothing at ≥60 °C.
If lice appear, how can they be eliminated? - in detail
When a head‑lice infestation is detected, immediate treatment prevents spread and reduces discomfort.
-
Apply an approved pediculicide containing either permethrin (1 %) or dimethicone (4 %). Follow the manufacturer’s instructions precisely: apply to dry hair, leave for the recommended duration, then rinse thoroughly. Repeat the application after seven days to eliminate newly hatched nits that survived the first treatment.
-
Use a fine‑toothed nit comb (spacing 0.2 mm) on wet, conditioned hair. Starting at the scalp, pull the comb through each strand to the ends, wiping the teeth after each pass. Perform this combing session every 2–3 hours for the first 24 hours, then twice daily for three consecutive days. Remove all visible nits and lice; discard the debris.
-
Decontaminate personal items and the environment. Wash clothing, bedding, and towels used within the previous 48 hours in water ≥ 60 °C, then tumble‑dry on high heat. For items that cannot be laundered, seal in a plastic bag for at least two weeks. Vacuum carpets, upholstery, and vehicle seats; discard the vacuum bag or clean the canister afterward.
-
Conduct a post‑treatment inspection 10 days after the initial application. Examine the scalp and hair under bright light; repeat the nit‑comb procedure if any live lice or viable nits are found. Maintain a weekly combing schedule for the next month to ensure complete eradication.
Adhering to this systematic approach—chemical treatment, meticulous combing, thorough environmental cleaning, and diligent follow‑up—eliminates head‑lice infestations effectively.
