With Advanced Climate Control anti-frizz products for curly hair, the fight against frizz starts in the shower. Ouidad's Defrizzing Shampoo is formulated to help your curls withstand humidity, heat, and other frizz-causing factors. 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, preventing frizz. A dedicated UV filter helps protect against damage from environmental aggressors. The result: defined, shiny, controlled curls - in any climate. No wonder it’s a favorite of curl experts in Ouidad salons across the U.S. For all curl types.
