If there's one thing that Jennifer Aniston has in common with the Duchess of Cambridge, it's their hair -- or at least the popularity of their haircuts. Both Aniston and Kate Middleton were recently named as having the most influential hairstyles in a new poll taken by women in Britain.

According to the Daily Mail on Wednesday, Aniston and Middleton made the list, with the former Friends star topping at no. 1 while the Duchess of Cambridge landing at 10th place.

Jennifer Aniston, Justin Theroux Put Their Wedding On Hold Again?

Meanwhile, Aniston is not just a hair icon but a beauty one these days, too. Just last month, Aniston opened up about her beauty regime to Yahoo, saying that her fiancé Justin Theroux would take to extreme measures to make sure she would never "mess with her face."

"There is this pressure in Hollywood to be ageless," Aniston told the site. "I think what I have been witness to, is seeing women trying to stay ageless with what they are doing to themselves. I am grateful to learn from their mistakes, because I am not injecting s--- into my face."

She added, "No honestly, I see them and my heart breaks. I think 'Oh god if you only knew how much older you look.' They are trying to stop the clock and all you can see is an insecure person who won't let themselves age. I also have a fiancé who will put a gun to my head if I touch my face in any way."

The actress also credited her father and his Greek roots for her ageless face.

She said, "My dad [soap opera veteran John Aniston] is 100 percent Greek; he turned 81 and he barely has a wrinkle. And neither did my grandmother, who was 95 when she died. But it's also just water, drinking a lot of water, using really nice good products for your face. Don't overproduce, that's the other thing. Getting proper sleep is always important."
