Heidi Klum's bronze complexion and sun-kissed highlights are the perfect canvas for her low-key summer hair: the beachy vibe we all want, while still looking polished and pretty. To get the look on your own getaway, work a dollop of volumizing spray or mousse through damp hair and either let it air dry or blow dry it rough, using your fingers. Next, try backcombing a few pieces slightly with a fine tooth comb for some added texture.
