Kate Hudson added lots of texture and volume to her version of the classic bun. Instead of a perfectly coiffed 'do, she went for casually lifted locks with a few sexy loose strands.
To get her look, begin by spritzing tresses with a little hairspray and tousle to add texture. Next, finger comb hair and secure in a high ponytail. Then, using a natural bristle hair brush, backcomb the ponytail and loosely twist it.
Wrap the twisted tail around the base and tuck ends into the hair elastic. Before pinning the bun in place, create additional volume by gently tugging on it. Once you've created the perfect size, insert u-shaped hair pins around the perimeter and mist with lots of hairspray.
We've spotted other celebrities with a similar look, including Claire Danes, Taylor Swift and Selena Gomez. Check out all the pictures in the Loose Bun Lookbook.
