How to use benzyl benzoate for lice? - in detail
Benzyl benzoate is a topical insecticide employed to eradicate head‑lice infestations. The product is supplied as a liquid concentrate that must be diluted before contact with the scalp. Follow these precise actions:
- Prepare a 10 % solution by mixing one part benzyl benzoate concentrate with nine parts water or a mild, non‑oil‑based shampoo. Stir until the mixture is uniform.
- Apply the solution to dry hair, ensuring complete saturation of the scalp and all hair shafts. Use a spray bottle or a cotton applicator to reach the nape of the neck and behind the ears.
- Allow the liquid to remain on the hair for 30 minutes. During this period, the active ingredient penetrates the exoskeleton of the lice and disrupts their nervous system.
- Rinse the hair thoroughly with warm water. Do not use conditioner or other hair products immediately after rinsing.
- Repeat the treatment after seven days. This second application eliminates any newly hatched nymphs that survived the first exposure.
Additional considerations:
- Use gloves while handling the concentrate to avoid skin irritation.
- Do not apply the solution to broken skin, irritated scalp, or mucous membranes.
- Keep the preparation out of reach of children; store at room temperature, away from direct sunlight.
- For infants under six months, consult a healthcare professional before use; benzyl benzoate is not recommended for this age group.
Effectiveness relies on strict adherence to the dilution ratio, contact time, and the repeat application schedule. Failure to observe any step reduces the likelihood of complete eradication.
