What works against lice at home? - briefly
A pediculicide shampoo (e.g., 1 % permethrin) applied to wet hair, followed by meticulous combing with a fine-toothed lice comb, removes most live insects, while laundering bedding, clothing, and vacuuming upholstery at ≥60 °C eliminates eggs. For those preferring non‑chemical methods, a thorough coating of olive oil mixed with tea‑tree oil, left on the scalp for 30 minutes before combing, also proves effective.
What works against lice at home? - in detail
Effective home remedies for head lice involve a combination of mechanical removal, chemical agents, and environmental measures.
Wet combing with a fine-toothed lice comb remains the most reliable method. Apply a generous amount of conditioner to damp hair, separate strands, and pull the comb from scalp to tip. Repeat every 2–3 days for two weeks, rinsing the comb in hot water after each pass.
Over‑the‑counter pediculicides containing permethrin (1 %) or pyrethrin with piperonyl butoxide can be applied according to package directions. Leave the product on the scalp for the specified time, then rinse thoroughly. A second application after 7–10 days eliminates newly hatched nymphs.
Alternative topical agents include dimethicone‑based lotions, which coat lice and prevent breathing. Apply liberally, cover with a plastic cap for 10 minutes, then wash hair with regular shampoo.
Natural substances such as tea‑tree oil, neem oil, or a mixture of 10 % vinegar and water may reduce infestation, but evidence is limited. Use only after a patch test to avoid scalp irritation.
Environmental control complements direct treatment. Wash all bedding, hats, and clothing worn within the previous 48 hours in hot water (≥ 130 °F) and dry on high heat. Items that cannot be laundered should be sealed in a plastic bag for two weeks. Vacuum carpets and upholstered furniture; discard vacuum bags immediately.
A concise protocol:
- Wet‑comb hair with conditioner, using a lice comb, every 2–3 days for 14 days.
- Apply a permethrin or dimethicone product, repeat after 7–10 days.
- Process all washable items in hot water and high‑heat dryer.
- Seal non‑washable items for 14 days; vacuum surroundings.
Adhering to this regimen eliminates live lice and prevents reinfestation without professional intervention.
