What should you do if lice are found on the head? - in detail
When live insects are detected on a scalp, begin with a thorough visual inspection. Use a fine-toothed comb on wet hair, starting at the roots and moving toward the tips. Separate sections to ensure every area is examined. If nits or adult lice are seen, record the location for later reference.
- Isolate the affected individual. Avoid sharing hats, brushes, or pillows until the infestation is resolved.
- Apply an approved pediculicide according to the product label. Common options include 1% permethrin lotion or 0.5% malathion shampoo. Follow the recommended contact time; do not exceed it.
- Rinse the hair thoroughly with lukewarm water. Dry with a clean towel; avoid heat styling that could damage the scalp.
After the initial treatment, repeat the combing process every 2–3 days for two weeks. Remove all visible nits with the fine-toothed comb, discarding them in sealed plastic bags. A second application of the insecticide may be required after 7–10 days, depending on the product instructions.
Environmental decontamination is essential. Wash bedding, clothing, 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 plastic bags for two weeks. Vacuum carpets, upholstered furniture, and car seats; discard the vacuum bag or clean the canister afterward.
Schedule a follow‑up examination after the treatment cycle. Confirm the absence of live insects and nits. If any remain, repeat the full protocol or consult a healthcare professional for alternative therapies, such as oral ivermectin.
To prevent recurrence, implement routine scalp inspections, especially in school‑age children. Encourage the use of personal hair accessories and discourage head‑to‑head contact during play. Maintaining clean, dry hair reduces the likelihood of future infestations.
