Sienna Miller's hair has done it all. It's been short and long, dark and light. The star has even made waves with a mind-blowing, beautiful shade of pink. She wears it up and down, sleek and tousled. Scan through these Sienna Miller hairstyles and find a new style to try for yourself.

Dark Locks
Usually seen as a blonde, Sienna went dark with her hair for the 2004 Academy Awards. Notice that the brown hair also made her blue eyes appear darker.

Pixie Cut
Sienna showed up at the 2005 premiere of "Casanova" with a short pixie cut. It was a carefree, swingy cut, and paired with her freckled nose and light pink lipstick, the blonde locks radiated summer chic.

Crowning Braid
Sienna took the braid to a whole new level with the wraparound look she wore for the 2007 Golden Globes. The halo of blonde, perfectly tousled hair was a stunning complement to her gold and cream dress.

Sleek Tresses
Sienna Miller's hair often features a tousled look, but she went smooth and sleek for the 2008 BAFTAs. The layered cut featured lip-length pieces in front and longer locks in back to accent the deep plunge in the back of her dress.

Glamorous Curls
Sienna Miller's hair channeled old Hollywood with Veronica Lake curls at a 2009 showing of "G.I. Joe: The Rise of Cobra". It was a fitting style, considering that the screening was held at the classic Grauman's Chinese Theater.

Long Locks
In 2009, Sienna had a long, layered cut. She parted it in the center and, not surprisingly, wore it in loose waves.

Pink and Gold
Sienna's version of pink hair wasn't a neon or bubblegum shade. Rather, in 2013, she went for a rose-gold color that embraced hints of both blonde and pastel pink. Between her pinkish hair and emerald dress, Sienna could have passed for a mermaid princess.

Eye-Grazing Bangs
Sienna tried out bangs for a 2013 awards show. Coupled with an updo, the look was elegantly playful.

Wavy Bob
With carefree waves and a deep side part, Sienna took the standard bob up a notch in 2014. The way the waves naturally frame her face just add to the wow factor.

Beachy Waves
Casual waves are one of Sienna's best hair looks. She's worn them both short and long. Here, her unevenly parted waves just hit her shoulders.

Deep Red
Sienna Miller's hair has even been red! She tried out an auburn dye job for the 2015 launch of her sister's fashion line.

Messy Ponytail
To attend screening of 'The Lost City Of Z' at Lincoln Center, Sienna pulled her hair into a loose ponytail. With volume near the back and loose pieces in front, it was messy without looking sloppy.

Casual Updo
With just one twist and pin, Sienna's long bangs were swept back from her face to complement an updo worthy of the red carpet.
