How long should benzyl benzoate be kept for lice? - in detail
Benzyl benzoate is applied as a single‑dose topical liquid for pediculosis. The standard protocol calls for a 30‑minute exposure followed by thorough rinsing. A second application is recommended 7–10 days after the first, to eliminate newly hatched nymphs that survived the initial treatment.
Key points for effective use:
- Initial treatment: Apply enough product to saturate the hair and scalp, massage gently, leave for 30 minutes, then wash with mild shampoo.
- Repeat dose: Re‑apply after a week‑plus interval; the same 30‑minute contact time is sufficient.
- Environmental control: Wash bedding, hats, and clothing in hot water (≥ 60 °C) or seal in plastic bags for at least 48 hours to prevent re‑infestation.
Maximum safety is achieved when the product is not left on the scalp longer than specified, as prolonged contact increases the risk of skin irritation. Following the two‑application schedule ensures that the life cycle of Pediculus humanus capitis is fully interrupted, resulting in complete eradication.
