How should vinegar be applied to hair to treat lice and nits? - briefly
Mix equal parts apple cider vinegar and water, saturate the scalp and hair, let it sit for 10–15 minutes, then rinse and comb with a fine‑toothed nit comb to remove lice and eggs. Repeat the process every 2–3 days for a week to eliminate any newly hatched nits.
How should vinegar be applied to hair to treat lice and nits? - in detail
Vinegar works by loosening the glue that holds nits to hair shafts and by creating an environment that discourages lice movement. Follow a systematic protocol to maximize effectiveness and minimize irritation.
-
Select the appropriate vinegar – Use distilled white vinegar or 5 % apple‑cider vinegar. Both have sufficient acidity (pH ≈ 2.5) to affect the nit attachment without excessive harshness.
-
Prepare the solution – Dilute vinegar with water in a 1:1 ratio. Undiluted vinegar may cause scalp discomfort, especially on sensitive skin or in children.
-
Pre‑treatment – Wash hair with a regular shampoo to remove excess oil and debris. Rinse thoroughly and towel‑dry until damp but not dripping.
-
Application – Pour the diluted mixture over the scalp and hair, ensuring complete saturation from root to tip. Massage gently for 30 seconds to distribute the liquid evenly.
-
Soak period – Cover the head with a plastic shower cap or a clean towel. Allow the vinegar solution to remain for 10–15 minutes. The duration permits the acid to penetrate the nit cement.
-
Comb out – Using a fine‑toothed nit comb, start at the scalp and work outward in small sections. Remove each nit before moving to the next segment. Wipe the comb with a moist cloth after each pass to prevent re‑attachment.
-
Rinse – Flush hair with lukewarm water. Follow with a mild conditioner if needed to restore moisture. Do not use hot water, which can close hair cuticles and trap residues.
-
Repeat schedule – Perform the entire process every 3–4 days for two weeks. This interval matches the lice life cycle and eliminates newly hatched nits before they mature.
-
Safety considerations – Avoid the method on open wounds, severely irritated scalp, or in individuals with known vinegar allergy. For infants under 6 months, substitute a pediatric‑approved lice treatment.
-
Environmental control – Wash bedding, clothing, and personal items in hot water (≥ 130 °F) or seal them in a plastic bag for two weeks to prevent reinfestation.
By adhering to these steps, vinegar serves as a practical adjunct to mechanical removal, reducing the number of viable nits and supporting overall lice eradication.
