How should lice and nits be properly eliminated? - in detail
Effective removal of head lice and their eggs requires a systematic approach that combines chemical treatment, mechanical extraction, and environmental control.
First, select an approved pediculicide containing either permethrin (1%) or dimethicone (10–30%). Apply the product according to the manufacturer’s instructions, ensuring thorough coverage of the scalp and hair. Leave the solution on for the recommended duration, then rinse with lukewarm water.
Second, eliminate surviving insects and unhatched eggs by combing. Use a fine-toothed lice comb on damp, conditioned hair. Perform the following steps:
- Divide hair into sections of 2–3 cm.
- Starting at the scalp, draw the comb through each section to the tip.
- Rinse the comb in a container of hot water after each pass.
- Repeat the process for the entire head, then re‑wet and repeat the combing session after 7–10 days to capture any newly hatched lice.
Third, decontaminate personal items and the surrounding environment.
- Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥60 °C) and tumble‑dry on high heat.
- Seal non‑washable items (e.g., hats, hair accessories) in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard the vacuum bag or empty the canister immediately.
Fourth, educate all affected individuals about preventive measures. Avoid sharing combs, hats, or hair accessories, and perform regular head inspections, especially after contact with known infestations.
Finally, monitor the situation for at least four weeks. If live lice are observed after two treatment cycles, consider a prescription‑only option such as benzyl alcohol or ivermectin, and consult a healthcare professional for guidance.
