How to eliminate lice eggs with hydrogen peroxide? - briefly
Apply 3 % hydrogen peroxide to the scalp, saturating the hair for 10–15 minutes, then use a fine-toothed lice comb to remove the nits before rinsing. Repeat the procedure after 7–10 days to eliminate any eggs that hatch later.
How to eliminate lice eggs with hydrogen peroxide? - in detail
Hydrogen peroxide can serve as a chemical agent that breaks down the protective coating of lice eggs, allowing them to be removed more easily. The procedure requires a solution of 3 % concentration, which is commonly sold as a wound‑cleaning antiseptic. Higher concentrations increase the risk of scalp irritation and should be avoided.
First, saturate a clean comb—preferably a fine‑toothed nit comb—with the peroxide solution. Apply the liquid directly to the hair and scalp, ensuring that every strand is thoroughly wet. Allow the solution to remain for 10–15 minutes; during this interval the peroxide penetrates the egg shell and weakens the adhesive that holds the egg to the hair shaft.
After the waiting period, use the comb to systematically work through the hair from the roots to the tips. Each pass should be followed by wiping the comb on a paper towel and re‑applying peroxide to the comb before the next section. Continue until no visible nits remain.
Key safety considerations:
- Perform a patch test on a small area of skin 24 hours before full application to detect possible 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, on individuals with open scalp wounds, or on people with known peroxide sensitivity.
- After treatment, rinse the hair with lukewarm water and a gentle shampoo to remove residual peroxide and prevent dryness.
To enhance effectiveness, repeat the process after 7–10 days, when any surviving eggs may have hatched. Combine the chemical treatment with regular combing sessions every 2–3 days to catch newly emerged lice before they reproduce.
Alternative options include dimethicone‑based lotions, which physically coat and suffocate lice, or prescription pediculicides. However, hydrogen peroxide remains a readily available, inexpensive choice when used correctly and with the precautions outlined above.
