Forget Frizz is a sulfate-free shampoo from amika formulated for medium-to-thick, coarse, wavy or coily hair that frizzes in humid conditions. Gentle cleansers (sodium cocoyl isethionate, cocamidopropyl betaine) wash hair without stripping it, while the brand's Extended Humidity Shield technology, along with water lily root extract and aloe leaf juice, is designed to seal the cuticle against humidity as it cleanses. Sea buckthorn and coconut oils add lightweight lipids, and a low-pH formula helps keep the cuticle smooth.
amika reports clinical testing showing up to 74% less frizz for up to 72 hours in high humidity when this shampoo is used as the first step of its anti-frizz system, alongside the matching conditioner and leave-in treatment. Used on its own, it still cleanses effectively while leaving hair smoother and less prone to humidity-driven frizz than a standard shampoo.
