How to get rid of lice with chemical water? - briefly
Mix a 1 % permethrin (or equivalent pediculicide) into water, saturate the hair and scalp, and keep it on for the manufacturer‑specified duration before rinsing. Repeat the treatment after 7–10 days to eradicate any surviving nits.
How to get rid of lice with chemical water? - in detail
Eliminating head‑lice infestations with a chemically treated aqueous solution requires a systematic approach that combines proper product selection, precise application, and thorough post‑treatment care.
Choose a formulation that contains an approved pediculicide such as permethrin, malathion, or dimethicone dissolved in water. Verify concentration levels on the label; typical dilutions range from 0.5 % to 1 % for permethrin‑based liquids, while dimethicone solutions may be undiluted. Avoid products that list unregistered or experimental compounds.
Prepare the solution according to manufacturer instructions. Use a clean container, add the recommended amount of the active ingredient to the specified volume of water, and stir until fully mixed. Ensure the mixture remains at room temperature; extreme heat or cold can reduce efficacy.
Apply the liquid to dry hair, saturating the scalp and all strands from root to tip. Use a fine‑tooth comb to distribute the solution evenly, paying special attention to the nape and behind the ears where lice and nits congregate. Leave the treatment on for the duration indicated—usually 10–15 minutes—then rinse thoroughly with lukewarm water.
After rinsing, remove dead insects and nits with a nit‑comb. Perform this step while the hair is still damp; repeat combing every 2–3 days for at least two weeks to capture any newly hatched lice. Wash all personal items (pillows, hats, brushes) in hot water (≥ 60 °C) or seal them in a plastic bag for 48 hours to prevent re‑infestation.
Monitor the scalp for signs of continued infestation—itching, live insects, or remaining nits—over the following week. If symptoms persist, a second treatment cycle may be necessary, adhering strictly to the recommended interval (typically 7–10 days) to target emerging lice before they mature.
Document the entire process, including product name, concentration, application time, and any adverse reactions. This record facilitates evaluation of effectiveness and informs future decisions should resistance or tolerance develop.
