amika: pro smooth over frizz fighting combo treatment set

discover a new way to smooth all hair types with this first-of-its-kind, salon-only service that fights frizz for 6-7 weeks.* this intensive smoothing treatment is formulated without formaldehyde or protein (plus, no harsh smell!) and powered by vegan ingredients like water lily extract, our signature superfruit sea buckthorn, and glyoxylic acid—an organic acid compound that restructures keratin in the hair cortex to smooth while increasing shine and manageability. when heat is applied to the hair, the glyoxylic acid creates a hydrophobic barrier—think of it like a raincoat for your strands—temporarily blocking humidity.
