How to get rid of lice using hydrogen peroxide? - briefly
Apply 3 % hydrogen peroxide to dry hair, saturating the scalp, leave for 10 minutes, then rinse thoroughly with warm water; repeat the treatment after 24 hours to target newly hatched nits. Follow with a fine-toothed comb to remove dead insects and residual eggs.
How to get rid of lice using hydrogen peroxide? - in detail
Hydrogen peroxide can be an effective agent for eradicating head‑lice infestations when applied correctly. The solution works by oxidizing the exoskeleton of the insects, causing dehydration and death. Follow these steps for a safe and thorough treatment:
- Purchase a 3 % hydrogen peroxide solution, the concentration commonly sold for household use. Higher percentages increase the risk of scalp irritation and should be avoided.
- Mix the peroxide with an equal part of water to reduce acidity and minimize discomfort. The resulting 1.5 % solution is sufficient for killing lice while remaining gentle on the skin.
- Dampen a clean spray bottle or a small bowl with the diluted mixture. Apply generously to dry hair, ensuring that the scalp and the entire length of each strand are saturated. The liquid must reach the nits attached to hair shafts.
- Cover the treated hair with a plastic cap or a shower cap. Keep the cap on for 10–15 minutes to allow the peroxide to act on the parasites.
- After the exposure period, rinse the hair thoroughly with lukewarm water. Use a fine‑toothed lice comb to remove dead insects and loosened nits. Comb from the scalp outward in sections, cleaning the comb after each pass.
- Repeat the entire process after 7 days, as any newly hatched nits will have emerged by then. A second treatment ensures complete eradication.
Precautions:
- Conduct a patch test on a small area of skin 24 hours before the first application to check for allergic reactions.
- Avoid contact with eyes; if accidental exposure occurs, rinse immediately with copious water.
- Do not use the method on children under two years of age or on individuals with open scalp wounds.
- Do not combine hydrogen peroxide with other chemical lice treatments, as interactions may increase irritation.
By adhering to the protocol above, hydrogen peroxide can serve as a cost‑effective, readily available option for eliminating head lice without resorting to prescription insecticides. Regular inspection of hair after treatment helps confirm success and prevents reinfestation.
