This 60-second in-shower rinse-out treatment is clinically shown to instantly reduce frizz by 73 percent and keep frizz reduced for up to 72 hours thanks to time-released humidity protection. It’s powered by smoothing superstars like glycolic acid—which helps to smooth the hair cuticle while creating a barrier to block out frizz—plus water lily extract and amika’s signature superfruit, sea buckthorn. The results: your hair, only 2.2x smoother.
