Whether you're a bronde, blonde or brunette, or looking for pixie-crop inspiration or fringe ideas, if you're on the hunt for hair inspiration pictures, we're guessing Sienna Miller will have made your list. After all, she's been a beauty crush of ours for as long as we can remember.

Miller's trademark style? Think relaxed and bohemian - she is the Queen of artful tousling. But that's not to say she doesn't often mix it up with the odd polished look or two. And while the actress often errs of the golden blonde side of life, these days she's opting for a different iteration of the hue - a shade coined 'Custard Cream Blonde,' by Harriet Muldoon at Larry King.

Of course, as to be expected with Miller, it's a trend that looks as delicious as it sounds.

'Custard cream blonde is going to be the hot colour for summer,' says Muldoon, a blonde expert who recently created the same hue for Kate Hudson. 'If you want to mimic Sienna's summery hair then ask your hairdresser for a blonde with a pale undertone of yellow to give it a rich, luxurious effect. Highlights should be lifted to a yellow undertone to allow for the warmth to come though. Ask for a liquid colour smudge on the base to blend out the blonde and leave a seamless effect.'

So if you're after more Sienna Miller hair inspiration, you've come to the right place. Sienna's not afraid to experiment with colour, having dabbled with being a brunette as well as an array of pastel colours. She's also no stranger to a more dramatic chop, having sported crops and mid-length styles over the years.
