How do you remove lice? - briefly
Apply a medicated shampoo with 1 % permethrin or a dimethicone‑based product, leaving it on the scalp for the time specified on the label. Then comb the hair with a fine‑toothed nit comb to extract dead insects and repeat the procedure in 7–10 days to prevent re‑infestation.
How do you remove lice? - in detail
Eliminating head‑lice infestations requires a systematic approach that combines immediate treatment, thorough cleaning, and ongoing monitoring.
Begin by confirming the presence of live insects and viable eggs (nits) attached to hair shafts within a half‑inch of the scalp. Use a fine‑toothed lice comb on damp hair to increase visibility and reduce slip.
Select a treatment method and apply according to product instructions. Common options include:
- Chemical pediculicides containing permethrin (1 %) or pyrethrin; apply to dry hair, leave for the recommended period, then rinse. - Dimethicone‑based lotions; coat hair thoroughly, allow to dry, and remove with a comb after 10 minutes. - Spinosad 0.9 % suspension; spray onto dry hair, wait 10 minutes, then rinse and comb. - Manual removal only; comb hair in sections, cleaning the comb after each pass with hot water.
After treatment, comb hair repeatedly for 7–10 days to capture any newly hatched nymphs. Perform combing at least once daily, using a fine‑toothed lice comb on wet, conditioned hair.
Simultaneously, decontaminate personal items. Wash clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 130 °F/54 °C) and tumble‑dry on high heat. Seal non‑washable items in sealed plastic bags for two weeks. Vacuum carpets, upholstery, and car seats to remove stray insects.
Implement preventive measures to reduce recurrence: avoid head‑to‑head contact, discourage sharing of hats, combs, or headphones, and routinely inspect hair of children in group settings. Early detection and prompt action limit spread and minimize the need for repeated chemical interventions.
