How to kill lice with vinegar? - in detail
Vinegar can be an effective component in a lice‑removal regimen when applied correctly. Its acidity helps dissolve the glue that secures nits to hair shafts, making them easier to extract.
Begin by preparing a solution of equal parts white distilled vinegar and warm water. Soak a clean comb in the mixture for a few minutes, then rinse. Apply the solution generously to dry hair, ensuring the scalp is covered. Allow it to sit for 5–10 minutes; during this time the liquid penetrates the egg coating.
After the waiting period, use a fine‑toothed nit comb to work through the hair from the roots to the tips. Comb each section several times, wiping the comb on a white towel after each pass to visualize removed material. Repeat the combing process at least twice a day for a week to catch any newly hatched insects.
For stubborn infestations, repeat the soaking step once daily for three consecutive days. Combine the vinegar treatment with a thorough washing of bedding, clothing, and personal items in hot water (minimum 130 °F) to prevent re‑infestation.
Safety considerations:
- Do not apply undiluted vinegar directly to the scalp; it may cause irritation.
- Test a small patch of skin before full application to check for allergic reaction.
- Avoid use on children under six months or on individuals with open wounds.
When executed consistently, this method can break the adhesive bond of lice eggs, facilitating their removal without the need for chemical pesticides.
