Sienna Miller is a great actress and the current style trend setter of UK high-street fashion.
Sienna's hair style is constantly changing going from long and short to blonde and brunette.
Sienna looks good with her Edie Sedgwick bob or long, boho waves.
Sienna's hair is naturally very thick and wavy and she adds five different shades of blonde and golden brown which lightens her hair for a sun-kissed effect.
To copy Sienna's hair style no matter what your hair length opt for a centre parting.
Use a texture hair spray and leave your hair slightly wavy (straighten your hair with Sedu straighteners and immediately put in braids - sleeping on your hair will make it look better too!).
If your hair is thick like Sienna Miller's, try the following for a different style!
1. After shampooing and conditioning as normal, apply mousse and gently towel-dry your hair. Blow-dry it roughly all over, using your fingers to lift and create volume.
2. Give yourself a centre parting, then scoop out your fringe area and leave this loose to frame your face.
3. Add volume to the roots by massaging your scalp with the pads of your fingers, then scoop your hair back into a low, loose ponytail and fix with a band.
To follow Siennas short style, leave your hair to dry naturally or give it a quick blast of a hairdryer for a more casual, messed up look. Without looking in a mirror rub a small amount of wax into your hands and work through to the ends of your hair for even distribution. Finally, gently tease into place with your fingers.
