For curls, once frizz sets in, there's no going back (at least without re-washing your hair). For truly frizz-free, smooth, and shiny curls, you have to prevent frizz before humidity wreaks havoc on your hair. With our new Advanced Climate Control Defrizzing Shampoo, the fight against frizz starts in the shower. This unique sulfate-free formula keeps hair's cuticle sealed to lock nourishing moisture in, and frizz-causing humidity out. Our advanced blend of emollients (Shea Butter, Murumuru Butter) and Ceramides helps repair the cuticle and smooth its surface. Our high-performance Anti-Frizz Nano Technology with a protein derived from silk seals the cuticle to form a barrier against frizz. A dedicated UV filter helps protect against damage from environmental aggressors. The result: defined, shiny, controlled curls-in any climate.
