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.
