amika: | pro smooth over frizz-fighting treatment - while most smoothing treatments alter hair’s natural pattern, this formula was developed to offer a smoothing solution for all hair types. to achieve this, there are two different applications & styling directions to better suit your specific hair needs.

this intensive smoothing treatment is formulated without formaldehyde or protein (plus, no harsh smell!) & is powered by vegan ingredients like water lily extract, superfruit sea buckthorn, and glyoxylic acid—an organic acid compound that restructures keratin in the hair cortex to smooth while increasing shine & 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.
