How do you use benzyl benzoate for lice? - in detail
Benzyl benzoate functions as a topical pediculicide applied directly to the scalp and hair. The standard preparation for head‑lice eradication contains 25 % benzyl benzoate in an oil‑based vehicle, providing sufficient penetration of the insect exoskeleton while minimizing irritation.
The procedure begins with a thorough wash of the hair using a mild shampoo. After rinsing, excess water is removed with a towel; the scalp must remain damp but not wet. The measured dose of the 25 % solution is applied evenly, ensuring coverage from the roots to the tips of all hair shafts. Application can be performed with a spray bottle or a dropper, followed by gentle massage to distribute the liquid across the entire scalp.
The following steps outline the complete regimen:
- Apply the solution to the entire head, covering all hair and scalp surfaces.
- Leave the preparation on for 30–45 minutes; this interval allows the active ingredient to act on both live lice and newly hatched nymphs.
- Rinse thoroughly with lukewarm water; a mild conditioner may be used to alleviate residual oiliness.
- Dry the hair with a clean towel or low‑heat dryer; avoid high heat that could degrade the residual compound.
A second treatment is required after 7–10 days to eliminate any surviving ova that hatched after the first application. During the interval, a fine‑toothed lice comb should be employed daily to remove dead insects and debris. All personal items—combs, brushes, hats, pillowcases, and bedding—must be washed in hot water (≥ 60 °C) or sealed in a plastic bag for at least 48 hours to prevent re‑infestation.
Safety considerations include avoiding use on broken or inflamed skin, on children under two years of age, and on individuals with known hypersensitivity to benzyl benzoate. Common adverse effects are mild erythema or itching; persistent irritation warrants discontinuation and medical consultation. The product should be stored in a tightly sealed container, protected from light and heat, at temperatures between 15 °C and 30 °C.
