Kérastase Ciment Thermique
We know, we know: Using flatirons and blow-dryers can weaken and dehydrate your hair—though we think walking around with a head full of frizz or a stunner of a cowlick is even worse. Which is why we refuse to put down the heat. But we've found an antidote: Kérastase Ciment Thermique ($34). Work a dollop of this conditioning treatment through hair to prevent breakage, smooth the cuticle (the hair's outer layer), and add shine. While our values may not be perfect, at least now our hair is.
