Our Advanced Climate Control formula prevents frizz 3 ways: Anti-Frizz Nano Technology with Sericin, a silk-derived protein, seals the cuticle to form a protective barrier against humidity. Secondly, a blend of Ceramides and emollients (Shea and Murumuru Butters) helps repair the cuticle and smooth its surface, while a dedicated UV filter helps protect against damage from environmental aggressors. The result: defined, shiny, controlled curls, and longer lasting frizz protection – in any climate. This travel set includes: STEP 1 Defrizzing Shampoo (2.5 oz): A unique, sulfate-free formula that gently cleanses and respects the hair’s natural protective barrier. Creates the perfect frizz-free foundation. STEP 2 Defrizzing Conditioner (2.5 oz): Hydrates, nourishes, and helps to repair with a balanced blend of emollients and Ceramides. Locks nourishing moisture in and frizz-causing humidity out. STEP 3 Detangling Heat Spray (2.5 oz): A nourishing detangler that provides a protective shield against heat damage and primes curls for a perfect frizz-free finish. STEP 4 Heat & Humidity Gel (2.5 oz): The best just got better. Our signature, award-winning formula provides frizz-free, flexible hold with exceptional curl definition that won’t leave hair crunchy, sticky, or weighed down. Now upgraded to include Anti-Frizz Nano Technology for advanced frizz protection.
