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.
