The key to fighting frizz is all about controlling moisture levels and locking the cuticle down as tight and smooth as possible. Unlike typical serum or oil-based humidity-fighting formulas that lay down a heavy coat on hair’s surface, (which deflate volume and leave the hair greasy) Dream Coat uses a groundbreaking, heat-activated polymer technology that is lighter than a feather. Dream Coat scatters teeny droplets randomly on hair’s surface. When heated with your blow-dryer these droplets connect and crosslink, forming an invisible, hydrophobic matrix that does two things:. Compresses each strand into a sleek, silky, supple shape Sheathes every strand in a light, imperceptible ‘raincoat’ that repels moisture Color chemicals leave hair porous and vulnerable to humidity. Dreaded moisture gets in – hair gets puffy, frizzes out! Dream Coat, inspired by new textile technology, covers each hair strand with an invisible waterproofing cloak.
