Advanced Climate ControlĀ® Heat & Humidity Gel gets you out of hair-raising situations. Use it to seal every strand, lock in moisture, and lock out humidity. Wheat Protein and pliable styling polymers form a weightless flexible lattice that expands as heat or humidity rises to hold curl definition without frizz. Anti-Frizz Nano Technology with a protein derived from silk seals the cuticle to keep essential moisture in and humidity out. A dedicated UV filter helps protect against damage from environmental aggressors.
