Jennifer Aniston's dowdy transformation for new movie Management reportedly cost a staggering £10,000 – and that was just for her hair.

The actress trades in her famous sun-kissed locks for a mid-brown bob to play travelling saleswoman Sue Claussen in the flick, which hit cinemas in the US this past weekend.

And apparently the low-key look didn't come cheap.

“She wanted to look very different but didn’t want to cut or dye her hair,” Jen's hairstylist on the movie, Melissa A. Yonkey, tells People.

So Jen's offscreen hair guru Chris McMillan was tasked with creating a $10,000 custom made wig, it's claimed.

“The color was very complimentary on her. She’s got wonderful warm skin,” explains Yonkey.

“With that blond hair, she’s very known as Jennifer Aniston and I think sometimes that takes away from watching the story."

Nice hair, shame about the film

Yonkey says that handling such hallowed hair didn't come without great responsibility.

“I was actually very, very concerned,” she says. “She’s so well-known for her hair that I was waiting for a lot of backlash. But I haven’t had it yet."

Despite the fancy hair, Management has hardly set the US box office alight so far - it opened with a disappointing $1,783 per screen average, compared with a $13,600 per screen average for Da Vinci Code sequel Angels & Demons.
