Best & Worst Beauty Of The Week: Kirsten Dunst, Sienna Miller, Anna Kendrick & More (PHOTOS)

This was a great week for celebrity hair. Sienna Miller made us want to go out and buy a floral headband, Kirsten Dunst sported some envy-inducing summer waves and fashion blogger and photographer Hanneli Mustaparta wore a sporty yet sexy updo.

While most of the hair this week was awesome, Rose McGowan wore her locks in a style that aged her, and both Jane Krakowski and Nicole Trunfio had a bad case of clumpy mascara.
