How to apply benzyl benzoate emulsion for lice? - in detail
Benzyl benzoate emulsion is a topical pediculicide that must be applied correctly to eradicate head‑lice infestations. Follow the procedure precisely to achieve maximum efficacy and minimize adverse reactions.
Prepare the scalp. Wash hair with a mild shampoo, rinse thoroughly, and towel‑dry until damp but not wet. Do not apply conditioner, hair spray, or oil, as these can form a barrier that reduces penetration.
Measure the required amount. The standard concentration is 25 % benzyl benzoate in an oil‑based emulsion. Use the supplied measuring cap or a calibrated dropper to deliver enough product to saturate the entire hair shaft and scalp, typically 5–10 ml for an adult, proportionally less for children.
Apply the emulsion. Part the hair in sections of 2–3 cm, using a fine‑toothed comb or your fingers. Dispense the liquid onto each section, ensuring every strand and the underlying skin are fully coated. Rub gently to spread the solution evenly; avoid excessive rubbing that could cause irritation.
Leave the preparation in place for the recommended contact time, usually 30 minutes. During this period, keep the head uncovered and maintain a comfortable room temperature. Do not wash, rinse, or towel‑dry the hair before the interval elapses.
Remove excess product. After the contact time, rinse the hair with lukewarm water and a mild, non‑medicated shampoo. Rinse thoroughly to eliminate residual emulsion. Dry the hair with a clean towel or allow it to air‑dry.
Comb out nits. While the hair is still damp, use a fine‑toothed nit comb to remove dead lice, nymphs, and eggs. Work from the scalp outward, cleaning the comb after each pass to prevent re‑contamination.
Repeat the treatment. A second application is required 7–10 days after the first to eradicate any newly hatched lice that survived the initial exposure. Follow the same preparation, application, and removal steps.
Observe for adverse effects. Mild skin irritation, redness, or itching may occur. If severe burning, swelling, or allergic reaction develops, discontinue use and seek medical attention.
Store the emulsion according to the label: tightly sealed, away from direct sunlight, and at room temperature. Keep out of reach of children.
Adhering to these instructions ensures that benzyl benzoate emulsion is used safely and effectively to eliminate head‑lice infestations.
