Our bestselling styler, Advanced Climate Control® 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.

A dedicated UV filter helps protect against damage from environmental aggressors.
