How to get rid of lice in hair? - briefly
Apply a permethrin‑ or pyrethrin‑based shampoo, follow the label’s contact time, then comb the hair thoroughly with a fine‑toothed lice comb to eliminate nits, repeating the process after 7–10 days. Clean personal items and bedding with hot water or seal them in plastic bags for two weeks to prevent reinfestation.
How to get rid of lice in hair? - in detail
Eliminating head‑lice infestations requires a systematic approach that combines chemical treatment, mechanical removal, and environmental control.
First, apply an approved pediculicide (permethrin 1 % or pyrethrin‑based shampoo) according to the product label. Leave the solution on the scalp for the specified duration, then rinse thoroughly. Repeat the application after seven to ten days to target any newly hatched nymphs that may have survived the initial dose.
Second, perform a meticulous combing session with a fine‑toothed nit comb. Separate hair into sections, start at the scalp, and pull the comb through each strand to the ends. Rinse the comb in hot water after each pass. Conduct this process daily for at least ten days, extending the period if live insects are still observed.
Third, launder all personal items that have contacted the head. Wash clothing, bedding, and towels in hot water (minimum 130 °F/54 °C) and dry on high heat for at least 20 minutes. Items that cannot be machine‑washed should be sealed in a plastic bag for two weeks, a duration sufficient to kill lice and eggs.
Fourth, vacuum carpets, upholstery, and vehicle seats to remove stray insects and shed eggs. Discard vacuum bags or empty the canister immediately after use.
Fifth, educate all household members about avoiding direct head‑to‑head contact and not sharing combs, hats, or hair accessories.
A concise checklist for successful eradication:
- Apply pediculicide as directed; repeat after 7–10 days.
- Comb hair daily with a nit comb for at least 10 days.
- Wash all washable items in hot water; dry on high heat.
- Seal non‑washable items for two weeks.
- Vacuum and discard vacuum contents.
- Enforce no‑sharing policies for personal hair items.
Following these steps consistently eliminates the parasitic infestation and prevents recurrence.
