We love rocker-chic bedhead as much as the next Alexa Chung, but this sculpted look just earned an invitation to our next cocktail hour. "I wanted the texture to be polished and shiny," says Adir Abergel, Reese Witherspoon's stylist, who added volumizing mousse and hydrating oil to wet strands. "I set the part at the arch of her brow, the most flattering placement for a side part, then blow-dried with a round brush until waves were smooth." Pull hair over one shoulder and hit with finishing spray. For extra support, "mist two bobby pins with spray, then cross them behind the ear."
