Adam Campbell for Dove Hair told In the Know that the inspiration for Portman's full and lived-in hair look "was effortlessly undone French girls."

"We created a simple but chic bob that perfectly frames and highlights her face, allowing for effortless glamour," he added.

The Black Swan leading lady's hair look only took four steps to create, but the voluminous element was solely achieved with a few spritzes of the Dove Refresh + Care Volume & Fullness Dry Shampoo. Campbell especially explained that they chose to use the affordable and highly-rated product "to give the hair a little volume and slept-in texture."
