How to delete lice? - briefly
Apply a fine-toothed comb to shampoo‑treated, damp hair, then wash clothing and bedding in hot water and vacuum the surroundings. Repeat the treatment every few days for two weeks to eradicate any remaining eggs.
How to delete lice? - in detail
Eliminating head lice requires a systematic approach that addresses the infestation on the person, in the environment, and prevents re‑infestation.
The first step is to confirm the presence of live nymphs or adult insects. Use a fine‑tooth comb on damp hair, inspecting the comb after each pass for insects or viable eggs (nits). If lice are detected, begin treatment without delay.
Chemical treatment
- Apply an over‑the‑counter pediculicide containing 1 % permethrin or 0.5 % pyrethrin, following the product’s instructions precisely.
- Leave the preparation on the scalp for the recommended duration, typically 10 minutes, then rinse thoroughly.
- Repeat the application after 7–10 days to kill newly hatched lice that survived the first dose.
Mechanical removal
- After the chemical step, comb the hair with a metal nit‑comb while the hair remains wet.
- Divide hair into sections; run the comb from scalp to tip, cleaning the comb after each pass.
- Perform this combing twice daily for three consecutive days, then once daily for the next week.
Alternative treatments
- Dimethicone‑based lotions suffocate insects; apply as directed and leave for at least 8 hours before washing.
- Heat therapy (e.g., a professional hot air device) raises scalp temperature to 50 °C for 30 seconds, killing lice instantly. Use only certified equipment.
Environmental decontamination
- Wash all clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes.
- Seal non‑washable items in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstery, and car seats; discard vacuum bags immediately after use.
- Avoid sharing combs, hats, or pillows until the infestation is cleared.
Follow‑up monitoring
- Inspect the hair and scalp 24 hours after the second chemical application. Absence of live insects confirms success.
- Continue weekly checks for four weeks to detect any resurgence early.
Prevention
- Encourage regular use of a fine‑tooth comb on dry hair to detect early infestations.
- Educate about avoiding head‑to‑head contact and not sharing personal items.
- In group settings (schools, camps), conduct routine screenings and isolate affected individuals until treatment is complete.
By adhering to the outlined chemical, mechanical, and environmental measures, lice can be eradicated efficiently and the risk of recurrence minimized.
