Oscars 2013 Best Hair and Beauty | Pictures

To achieve Jessica Chastain's vintage waves, stylist Renato Campora first created a deep side part in the actress's hair. He then blow-dried her strands with Vidal Sassoon Foaming Air Mousse ($4, originally $5), using a round brush for added volume. After curling her hair and pinning it up until cool, he brushed out the style and spritzed it with hair spray to finish.
