Instructions For Use

Completely cover the scalp with Natroba™ Topical Suspension.

Lice and nits live near the scalp. Use as much product as needed to completely cover the scalp first, and then apply outwards towards the ends of the hair.

For very thick, medium length hair or long hair, an entire bottle (120mL) of Natroba™ Topical Suspension may be needed to cover the scalp and hair.

Less Natroba™ Topical Suspension may be needed for shorter, thinner hair. Children will need an adult to apply Natroba™ for them.

Consult the Patient Information and your doctor for more complete information on Natroba™.
