Daily styling can mean damage to your tresses. To have silky strands like Sienna Miller, it's important to use a heat protectant product before using any heat on the hair.

Get her look: Apply heat protectant to wet hair, make a center part, then blow-dry hair smooth with a medium round brush. To coax subtle waves, wrap the ends of hair around the brush, and blast with heat, then hold the brush for a few seconds. Let cool for the style to set, then release brush. Finish with a light hairspray for hold.
