What should be done if I have lice on my head? - in detail
If head lice are detected, immediate action is required to prevent further spread and eliminate the infestation.
The first step is to confirm the presence of live insects or viable eggs (nits) attached to hair shafts close to the scalp. Use a fine‑toothed comb on wet, conditioned hair, examining each section under good lighting.
Next, choose an appropriate treatment method:
- Apply a medicated lice shampoo or lotion containing 1 % permethrin, 0.5 % pyrethrin, or dimethicone. Follow the product’s instructions precisely, leaving the solution on the scalp for the recommended duration before rinsing.
- For resistant cases, consider a prescription‑only preparation such as malathion 0.5 % or ivermectin 0.5 % lotion, administered under medical supervision.
After treatment, remove residual nits with a fine‑toothed comb. Perform combing at least twice daily for ten days, focusing on the nape, behind the ears, and any dense hair areas.
Simultaneously, address the environment:
- Wash all recently worn clothing, bedding, and towels in hot water (≥ 60 °C) and dry on high heat.
- Seal non‑washable items in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstered furniture, and car seats to collect stray lice and nits.
Prevent re‑infestation by educating all household members about avoiding head‑to‑head contact, not sharing personal items such as hats, hairbrushes, or headphones, and conducting regular inspections, especially after school or camp attendance.
If symptoms persist beyond the recommended treatment period, schedule a follow‑up with a healthcare professional to evaluate alternative therapies or confirm eradication.
