What can be used to get lice off hair? - in detail
Lice infestation requires prompt elimination to prevent spread and discomfort. Effective control combines topical agents, mechanical extraction, and environmental sanitation.
Chemical agents approved for lice eradication include:
- Permethrin 1 % lotion, applied to dry hair for ten minutes before rinsing.
- Pyrethrins combined with piperonyl‑butoxide, applied similarly to permethrin.
- Dimethicone (5 %–10 %) silicone‑based lotion, suffocates insects without neurotoxic action.
- Malathion 0.5 % solution, reserved for resistant cases, applied for eight to twelve hours.
Each product must be used according to manufacturer instructions, with attention to age restrictions and potential skin irritation.
Mechanical removal relies on a fine‑tooth nit comb. Recommended procedure:
- Saturate hair with conditioner to reduce slip.
- Divide hair into sections of 2–3 cm.
- Pass comb from scalp to tip, removing lice and nits after each pass.
- Rinse comb frequently in hot water.
- Repeat process daily for seven days, then once more after twelve days to capture newly hatched lice.
Adjunctive home treatments may aid chemical or mechanical methods. Application of mineral oil, olive oil, or petroleum jelly for thirty minutes creates a barrier that impedes breathing. Afterward, combing removes immobilized insects. Such oils should be washed out thoroughly to avoid scalp greasiness.
Environmental measures limit re‑infestation:
- Wash bedding, clothing, and towels in water ≥ 60 °C, or dry‑clean if temperature unsuitable.
- Seal non‑washable items in sealed plastic bags for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags promptly.
Follow‑up examinations at day 7 and day 14 confirm eradication. Persistence of live lice after two treatment cycles warrants consultation with a healthcare professional for alternative regimens.
