How to dilute vinegar to remove lice? - briefly
Mix one part white distilled vinegar with three parts water, apply the solution to the scalp and hair, let it sit for 10–15 minutes, then comb out the lice and nits. Rinse thoroughly and repeat the treatment after 48 hours to eliminate any newly hatched insects.
How to dilute vinegar to remove lice? - in detail
To use vinegar as a lice‑removing agent, the solution must be sufficiently diluted to avoid scalp irritation while retaining enough acidity to loosen nits. A typical ratio is one part white distilled vinegar (5 % acetic acid) to three parts water, yielding a 1.25 % acetic acid mixture. For a stronger preparation, increase vinegar to two parts and water to one part, resulting in a 3.3 % solution; this concentration should be tested on a small skin area first.
Preparation steps
- Measure the required volumes with a graduated container.
- Combine vinegar and water in a clean, sealable bottle.
- Shake gently to ensure uniform distribution.
- Label the bottle with concentration and preparation date.
Application procedure
- Apply the diluted solution to dry hair, saturating the scalp and strands from roots to tips.
- Allow the liquid to remain for 10–15 minutes; the acidity softens the glue that attaches nits to hair shafts.
- Use a fine‑tooth nit comb, starting at the scalp and moving outward, to remove loosened nits and adult lice.
- Rinse hair thoroughly with lukewarm water; avoid hot water, which can cause additional irritation.
- Repeat the process after 7 days, when any surviving eggs have hatched, to eliminate any newly emerged lice.
Safety considerations
- Conduct a patch test on the inner forearm for 5 minutes before full application; discontinue if redness or burning occurs.
- Do not use undiluted vinegar, as the 5 % acidity can cause severe scalp discomfort.
- Keep the solution out of reach of children and pets.
- Store the mixture in a cool, dark place; discard after two weeks to prevent bacterial growth.
