How can lice be removed with vodka? - briefly

Apply vodka to the scalp and hair, saturating the area, then use a fine-toothed comb to remove the dead lice and nits. Rinse thoroughly afterward and repeat the process if any remain.

How can lice be removed with vodka? - in detail

Vodka can serve as a solvent for dissolving the protective coating on head‑lice, allowing the insects to desiccate and die. The alcohol content (typically 40 % ethanol) penetrates the exoskeleton, disrupting the lipid layer that prevents water loss. When the coating is compromised, the lice lose moisture rapidly, leading to mortality within minutes.

Procedure

  1. Preparation – Choose a high‑proof, unflavored vodka. Dilute with equal parts water only if the alcohol concentration is above 70 % to reduce irritation; otherwise use straight vodka.
  2. Application – Saturate a clean cotton ball or spray bottle with the liquid. Apply generously to the scalp, ensuring coverage of hair shafts, roots, and behind the ears.
  3. Contact time – Leave the solution on for 5–10 minutes. The ethanol continues to act while the hair remains damp.
  4. Removal – Comb the hair with a fine‑toothed lice comb, starting at the scalp and working toward the ends. The dead insects will be dislodged and can be collected on the comb.
  5. Rinse – Wash hair with a mild shampoo to eliminate residual alcohol and any remaining debris.
  6. Repeat – Perform the treatment every 2–3 days for a week to address newly hatched nymphs, as eggs (nits) are resistant to alcohol.

Safety considerations

  • Test a small skin area before full application to check for allergic reaction or irritation.
  • Avoid use on children under two years, pregnant individuals, or persons with open scalp wounds.
  • Do not combine with other chemical pediculicides, which may increase toxicity.
  • Ensure adequate ventilation to prevent inhalation of vapors.

Effectiveness

Scientific studies on ethanol’s insecticidal properties show rapid dehydration of ectoparasites. While vodka lacks the potency of concentrated ethanol, the repeated exposure described above achieves comparable lice mortality rates when applied correctly. Success depends on thorough coverage and consistent follow‑up sessions.

By adhering to the steps outlined, vodka functions as a low‑cost, readily available agent for eliminating head‑lice infestations without resorting to prescription medications.
