To achieve the look, Ramona Eschbach for Oribe Hair Care started by blow-drying Dianna's hair with volume-enhancing products. She then applied the brand's Dry Texturizing Spray ($39) at the roots, followed by Impermeable Anti-Humidity Spray ($38) from the midshaft to ends. After backcombing Dianna's strands at the roots, Eschbach then tied the actress's hair into a low ponytail, twisting and securing the swinging '60s style into place with pins. Yeah, baby, yeah.
