How should Barss lice treatment for humans be used? - in detail
Barss lice medication is a topical preparation intended for eradication of head‑lice infestations in individuals. The product must be applied according to the following protocol.
- Preparation: Verify that the affected person is at least 6 months old and does not have open wounds, eczema, or allergic reactions to any component. Remove hair accessories and comb out tangled hair with a fine‑toothed comb.
- Dosage: Use the supplied applicator to dispense the entire contents onto the scalp, covering the hair from the neck to the forehead. Ensure thorough saturation of each strand.
- Contact time: Leave the solution on the scalp for the period specified on the label, typically 10 minutes. During this interval, the person should remain seated and avoid washing the hair.
- Rinsing: After the prescribed time, rinse the hair with lukewarm water. Do not use shampoo or conditioner immediately; wait at least 30 minutes before applying any other hair products.
- Second treatment: Perform a repeat application 7‑9 days after the first, regardless of symptom resolution, to eliminate newly hatched nymphs.
- Post‑treatment combing: At least 24 hours after each application, use a fine‑toothed nit comb to remove dead lice and nits. Comb the entire head in sections, cleaning the comb after each pass.
- Environmental control: Wash bedding, hats, and hair accessories in hot water (minimum 130 °F/54 °C) and tumble‑dry on high heat. Items that cannot be laundered should be sealed in a plastic bag for two weeks.
Precautions
- Do not apply to children younger than six months, pregnant or nursing women unless directed by a healthcare professional.

- Store the container at room temperature, away from direct sunlight and out of reach of children.
Contraindications
