Immediately apply an approved pediculicide and comb out nits with a fine-toothed device; then launder clothing, bedding, and personal items in hot water. Repeat the treatment after seven days to eliminate any newly hatched lice.
Lice have appeared, what should you do? - in detail
When head‑lice are detected, immediate action prevents spread and reduces discomfort.
First, confirm the presence of live insects or viable eggs by examining hair close to the scalp with a fine‑toothed comb.
Next, apply an approved pediculicide according to the manufacturer’s instructions. Preferred options include permethrin 1 % lotion, dimethicone‑based creams, or malathion 0.5 % solution. After the recommended exposure time, rinse thoroughly and repeat the treatment after seven to ten days to eliminate newly hatched nymphs.
Simultaneously, remove all viable eggs and adult insects manually. Use a metal comb with 0.2‑mm teeth; work from the scalp outward, cleaning the comb after each pass. Perform this combing daily for at least one week.
Environmental decontamination limits re‑infestation.
- Wash bedding, towels, and clothing used within the previous 48 hours in hot water (≥ 60 °C) and dry on high heat.
- Seal items that cannot be laundered in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags immediately.
Family members and close contacts should be inspected. If live lice are found, repeat the treatment protocol.
Finally, educate all parties about detection signs and preventive measures: avoid sharing hats, hair accessories, or personal grooming tools; discourage head‑to‑head contact during play; and conduct regular scalp checks during outbreaks.
Adherence to this systematic approach eliminates the infestation and minimizes recurrence.
