How should chlorine water be used for lice, instructions? - in detail
Chlorinated water can be employed as a supplemental measure for managing head‑lice infestations when used correctly. The procedure requires precise preparation, application, and post‑treatment care to maximize efficacy and minimize risk.
Prepare a solution with a chlorine concentration of 0.5 % (approximately 5 g of household bleach per litre of water). Mix the bleach and water in a clean container, stirring until uniform. Allow the solution to stand for five minutes to ensure full activation of the chlorine.
Before application, separate the hair into manageable sections using a fine‑tooth comb. Wet each section with the prepared solution, ensuring the scalp and hair shafts are thoroughly saturated. Maintain the wetness for ten minutes; this exposure period permits the chlorine to penetrate the lice exoskeleton and disrupt their respiratory system.
After the exposure interval, rinse the hair with lukewarm water to remove residual chlorine. Follow the rinse with a gentle shampoo to cleanse the scalp. Comb the hair again with a lice‑comb to extract dead insects and nits. Dispose of the combed material in a sealed bag.
Repeat the entire process after 7–10 days, as newly hatched lice may emerge from eggs that survived the initial treatment. Avoid using the chlorine solution more frequently than once a week to prevent scalp irritation. Store any unused solution in a labeled, airtight container, and discard it after 24 hours.
If irritation, redness, or allergic reaction occurs, cease use immediately and seek medical advice. Chlorine water should complement, not replace, approved pediculicidal products and thorough environmental cleaning.
