Mark Townsend, hair stylist for Allison Williams, says he opted for "classic, all-American" beauty to compliment her understated dress (from Ralph Lauren). Here's how it happened:
"I started by applying a large dollop of the Dove Style+Care Nourishing Curls Whipped Cream Mousse to her damp hair and blow-dried with a medium-round brush to get lots of volume and keep her hair smooth," he says.
Townsend then took three- to four-inch sections of hair and curled them with a one-inch curling iron, moving away from Williams' face. To break up the curls, he scrunched the hair while spraying Oribe Après Beach spray all over.
For a little piecey-ness through William's tresses, Townsend spritzed Sally Hershberger's Glam Waves onto his hands and then raked his fingers through the ends.
To get her perfect waves to stay intact long past network parties, Townsend gave the actress' hair a halo of Dove Style+Care Extra Hold Hairspray to keep her hair full and shiny without looking stiff.
