What should be done if lice appear on the head? - briefly
Apply a pediculicide shampoo or lotion according to the label, then comb the hair with a fine‑toothed nit comb to eliminate lice and nits. Wash bedding, clothing, and personal items in hot water or seal them in plastic bags for two weeks to prevent re‑infestation.
What should be done if lice appear on the head? - in detail
Lice on the scalp require swift confirmation and action. Examine the hair with a fine‑toothed comb under bright light; live insects and viable eggs (nits) appear as brown or tan ovals attached close to the scalp. Capture a few specimens for verification if uncertainty remains.
Treat the infestation promptly with one of the following methods:
- Chemical pediculicides – apply a 1% permethrin or 0.5% pyrethrin lotion according to the product label, leave for the recommended time, then rinse thoroughly.
- Prescription agents – for resistant cases, use malathion 0.5% or ivermectin lotion as directed by a healthcare professional.
- Mechanical removal – comb wet hair with a nit‑comb at 5‑minute intervals for three consecutive days; repeat every 48 hours for two weeks to catch newly hatched nymphs.
Simultaneously address the environment to prevent re‑infestation:
- Wash all 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, plush toys) in sealed plastic bags for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags immediately.
Schedule follow‑up examinations at 7‑day and 14‑day marks. If live lice persist, repeat the chosen treatment or switch to an alternative chemical option under medical guidance.
Implement preventive strategies to reduce future risk:
- Instruct children to avoid head‑to‑head contact during play.
- Prohibit sharing of combs, hats, hair accessories, and pillows.
- Perform routine checks in schools or group settings, especially after known outbreaks.
Adhering to these precise measures eliminates current infestation and minimizes the likelihood of recurrence.
