Please give our sincerest condolences to flat irons everywhere: they'll be of no use to you after you try the Garnier Fructis Sleek Shot In-Shower Styler ($5). The brilliant in-shower treatment combines hydrating argan oil with an innovative flexible polymer that cuts down your blow-dry time for sleek, Ariana Grande hair on a just-hit-snooze schedule. Simply squirt a dollop into your shampoo, wash, condition, and go . . . then try to figure out what to do with all those extra minutes you now have in your day.
