"I have the kind of hair that poufs up in a decidedly un-cute way at the mere mention of humidity, so fighting frizz is always top of mind. I usually rely on products that I apply to damp or dry hair to get the job done, but the Garnier Fructis Sleek Shot In-Shower Styler ($5) has become a mainstay in my routine. The application is a bit unconventional but not complicated: mix one part Sleek Shot with one part shampoo and lather, rinse and follow with conditioner as usual. I could tell the first time I blow-dried my hair after using it that it was going to be a game-changer. My hair felt smooth, soft and looked extra shiny. I don't what kind of wizardry is in this magical hair product (and to be honest, I'm not sure I want to), but I haven't turned on my flatiron since I started using it." — Lindsey Unterberger, assistant editor, Makeup.com
