How can you dilute vinegar for lice removal? - in detail
Diluting vinegar reduces acidity, making it safer for scalp contact while still retaining the ability to loosen lice eggs. Use a white distilled vinegar with 5 % acetic acid as the base.
Measure one part vinegar to three parts water (1 : 3 ratio). For example, combine ¼ cup (60 ml) of vinegar with ¾ cup (180 ml) of lukewarm tap water. Stir until the mixture is uniform. If the scalp is sensitive, increase the water proportion to a 1 : 4 ratio.
Transfer the solution to a spray bottle or a clean container with a lid. Apply generously to dry hair, ensuring the mixture reaches the roots and the nape of the neck. Let it sit for 5–10 minutes; the liquid softens the cement that holds nits to hair shafts.
After the waiting period, use a fine-toothed nit comb to remove lice and nits. Comb from the scalp outward, wiping the comb after each pass. Rinse hair with mild shampoo to eliminate residual vinegar odor.
Repeat the treatment every 2–3 days for one week to address newly hatched lice. Store any unused diluted solution in a sealed bottle in a cool, dark place; discard after 48 hours to prevent bacterial growth.
Safety notes: Do not apply undiluted vinegar directly to the scalp, as it may cause irritation or burning. Perform a patch test on a small area of skin 15 minutes before full application. Avoid use on broken skin, open wounds, or children under two years of age without medical advice.
