How to remove lice from a child using hydrogen peroxide? - briefly
Apply a 3% hydrogen peroxide solution, gently misting the scalp and hair, let it sit for 5‑10 minutes, then use a fine-toothed lice comb to remove nits and adult lice; repeat the treatment after 7‑10 days to eliminate any newly hatched insects.
How to remove lice from a child using hydrogen peroxide? - in detail
Hydrogen peroxide can be employed as a lice‑killing agent when applied correctly. Begin by selecting a 3 % solution, the concentration commonly sold for household use. Higher percentages increase the risk of skin irritation and should be avoided.
Preparation
- Test a small area of the child’s scalp for sensitivity by applying a few drops of the solution, waiting five minutes, and observing for redness or burning.
- Gather a fine‑toothed lice comb, a clean towel, and a shallow bowl.
- Ensure the child’s hair is dry; moisture reduces the peroxide’s effectiveness.
Application
- Pour enough peroxide into the bowl to saturate the hair, typically 2–3 ml per 10 cm of scalp.
- Using a disposable dropper or a spray bottle, distribute the liquid evenly over the entire scalp, concentrating on the nape, ears, and behind the shoulders.
- Allow the solution to remain for 10 minutes. The peroxide will foam, disrupting the lice exoskeleton and dissolving the glue that holds nits to hair shafts.
Removal
- After the exposure period, cover the hair with a towel to absorb excess liquid.
- While the hair is still damp, run the lice comb through small sections from root to tip, wiping the comb blade on a paper towel after each pass.
- Repeat the combing process for the entire head, ensuring no strand is missed.
Post‑treatment care
- Rinse the scalp with lukewarm water; avoid hot water, which can increase irritation.
- Pat the hair dry with a clean towel; do not rub vigorously.
- Wash all clothing, bedding, and personal items that may have contacted the scalp in hot water (≥ 60 °C) or place them in a sealed bag for two weeks to starve any remaining insects.
Follow‑up
Perform a second combing session 7–10 days after the initial treatment to eliminate any newly hatched lice. If live insects are observed after the second round, repeat the peroxide application once more, observing the same safety precautions.
Safety considerations
- Do not use concentrations above 3 % without medical supervision.
- Discontinue use if the child experiences persistent burning, swelling, or allergic reaction; seek pediatric advice.
- Keep peroxide away from eyes; flush immediately with water if contact occurs.
When executed with these steps, hydrogen peroxide provides an effective, low‑cost method for eradicating head lice while minimizing chemical exposure.
