Sienna Miller's shorter haircut was a "brave" move.
The 'American Sniper' actress chopped her long locks earlier this year, a move Luke Hersheson - the celebrity hairdresser who created her new style - says she had been planning for a long time.
He said: "She was always quite a long hair girl because she was such an icon for the whole boho thing, so it was a massive deal for her to cut it, it was brave.
"But it was always the plan to cut it off at some point, to find the right moment and the right thing.
"You always need to change your trademark. It keeps you fresh and a trendsetter, when you're prepared to let go of what people think is your 'thing'."
While Sienna - who has a three-year-old daughter, Marlowe, with ex-fiancé Tom Sturridge - has cut her hair, she has still shown off a number of different styles with her locks and her hairdresser, Earl Simms, thinks they all looked "amazing".
He told Grazia magazine: "There were so many different styles, sometimes two or three changes a day.
"It was hectic, but Sienna is so versatile and looks amazing in many different looks."
