Allison Williams, GirlsDerek Storm / Splash News

At the premiere of HBO’s Girls in New York City, Allison Williams (daughter of newsanchor Brian Williams) showed off her perfect frizz-free waves. “To create these sexy, cascading waves for Allison, I started off with a blow drying spray on the scalp and then smoothed gel through the ends,” her hairstylist Ted Gibson told InStyle.com, adding that he used products from his own line (tedgibsonbeauty.com). He then wrapped one-and-a-half inch sections around a large barrel curling iron. “I finished off with a light hold hairspray for instant sex appeal.” We love it!
