From Alexander Wang to Theyskens' Theory, effortlessly cool straight hair was all the rage on the Fall 2012 runways. To counteract the bulk of heavy sweaters and cold-weather jackets, stylists stripped down their models' hair and kept it straight and shiny. The most important part of getting this urban-chic look right is to give your hair a good prepping. Keep reading to see how.

At Rachel Roy's show (pictured), hair guru Ted Gibson slathered on his antifrizz Tame It Shine Lotion ($20) to models' hair before blow-drying. This lightweight formula allows for freedom of movement while packing a serious punch when it comes to shine. And since there's flat-ironing involved in this type of style, you'll want to make sure you spritz on a thermal protecting spray before your strands touch the hot plates. But don't go too crazy with the straightening; the look is all about encouraging hair to flow freely. Finally, for an extra dose of luminosity, lightly run a shine-enhancing product through your coiffure, like Moroccanoil ($15), to tame and protect.
