How to get rid of lice with hydrogen peroxide? - briefly

Apply 3% hydrogen peroxide directly to the hair and scalp, let it sit for 5–10 minutes, then rinse and use a fine-toothed comb to remove lice and nits; repeat the treatment after 24 hours to ensure any newly hatched insects are eliminated.

How to get rid of lice with hydrogen peroxide? - in detail

Hydrogen peroxide can serve as an effective agent against head‑lice when applied correctly. The solution works by oxidizing the exoskeleton of the insects, leading to rapid dehydration and death. Follow a systematic protocol to maximize results and minimize irritation.

Begin by selecting a 3 % hydrogen peroxide solution, the concentration commonly available in pharmacies. Higher concentrations increase the risk of scalp burns and should be avoided. Prepare a clean, shallow bowl and pour enough liquid to fully submerge the hair.

1. Pre‑treatment preparation

   • Comb hair gently to remove tangles; loose strands allow better penetration.
   • Separate hair into sections of 2–3 cm using hair clips.

2. Application

   • Saturate each section with the peroxide, ensuring the scalp and hair shafts are completely wet.
   • Allow the liquid to remain for 5–10 minutes; longer exposure may cause excessive dryness.

3. Mechanical removal

   • After the waiting period, rinse hair with lukewarm water.
   • Use a fine‑toothed lice comb, moving from scalp outward in short strokes.
   • Wipe each comb tooth with a tissue after every pass to prevent re‑depositing live lice.

4. Post‑treatment care

   • Wash hair with a mild, sulfate‑free shampoo to eliminate residual peroxide.
   • Apply a lightweight conditioner to restore moisture.
   • Repeat the entire process after 7–10 days, targeting any newly hatched nymphs that escaped the first round.

Safety considerations: conduct a patch test on a small area of skin 24 hours before full application to detect possible allergic reactions. Discontinue use if burning, itching, or redness intensifies. Do not use on children under two years of age or on individuals with open scalp wounds.

Combining chemical action with thorough combing offers the highest likelihood of eradicating an infestation. Consistent follow‑up treatments and proper hygiene—regular laundering of bedding, hats, and brushes—prevent re‑infestation.
