A daily treatment for thick to coarse frizzy hair, No Frizz Straight Styling Treatment eliminates frizz and contains twice the emollient than our creams, just what thick, coarse hair requires. The treatment leaves hair manageable, sleek and shiny with natural movement. No Frizz features PolyfluoroEster - the first new anti-frizz technology in 30 years to effectively block humidity for beautifully soft, silky, frizz-free hair. Terrific for highly processed or colored hair.
