Lawrence's hairstylist, David Babaii, wanted to create a "high fashionista look" for the star, and judging by the graphic part and high-shine finish, we think he succeeded! The key to an ultra-sleek style that won't quit is to create a good foundation. Babaii used a few drops of IT&LY's Pure Water Drops ($30; sleekhair.com) on Lawrence's hair before blowing it completely straight with a round brush. Be sure to work in sections so you can make each area as smooth as possible. After parting hair to the side, Babaii locked in the straight texture by giving the style a quick pass with a flat iron.
