Keira Knightley Admits She's Been Wearing A Wig For The Past Five Years

Keira Knightley admitted Thursday that she's been wearing a wig for the past five years, telling InStyle Magazine that years of dyeing and styling her hair for her various film roles has caused her natural hair to fall out.

"I have dyed my hair virtually every color imaginable for different films. It got so bad that my hair literally began to fall out of my head! So for the past five years I've used wigs, which is the greatest thing that's ever happened to my hair."

She also noted that having a baby -- 15-month-old daughter Edie, whom she and husband James Righton welcomed in May -- has wreaked havoc with her hair.

"I have naturally crazy, curly hair, and since I've had the baby it's become 10 times thicker."

The 31-year-old Knightley, born in London in 1985, has been acting since she was a little girl. As a teen, she began making a name for herself with roles in Star Wars: Episode 1 - The Phantom Menace and Bend It Like Beckham.

Her breakout role came when she appeared, as a 17-year-old, in the first film in the Pirates of the Caribbean franchise. Since then, she's appeared in Pirates sequels as well as critically-acclaimed films such as The Imitation Game and Pride & Prejudice, according to Biography.

"I do a lot of period pieces because that's my taste, because I want to work in Europe, because that's my home and generally speaking that's what's made in England. I love history, you know, but actually because they've been the most interesting characters for me that I've been offered."

By 2008, Knightley had become the second-highest-paid actress in the movie industry.

In 2011, Keira began dating James Righton, keyboardist for the band Klaxons, and the couple got married in 2013.

Besides her film and TV work, Keira has also been actively involved in charitable causes, working with Amnesty International, WaterAid, and the American Library Association. And in 2009, her charitable work got a little bit too real, to some observers, when she appeared in a controversial anti-domestic-abuse video for Women's Aid. Some called the video too graphic, while others praised it for its accurate portrayal of domestic abuse.

On less weighty matters, Keira spoke to InStyle this week about the differences in beauty standards when it comes to American versus the United Kingdom.

"I think we Brits are very low-maintenance. For good or bad, you rarely walk around New York or LA and see women as grungy as you do in London. In the US they always have their hair and nails done, which isn't big culturally in England."

She's also learned that makeup only goes so far when it comes to beauty; it has as much to do with diet and lifestyle as it does with the product.

"I tried a million products, but none of them worked. I had bad skin up until I was 25. I later learned that it was more about diet and hormonal changes."

So now that Keira Knightley has admitted that she wears wigs, are wigs -- once de rigeur for fashionable women -- poised to make a comeback? According to an April 2015 InStyle report, wigs have been back for a long time in Hollywood, but apparently, no one wants to admit it.

"Hollywood's best kept secret, you'd be amazed at how many A-list celebs rock wigs on the red-carpet. Trust us, it's a lot."
