As it turns out, Blair Waldorf and Leighton Meester probably wouldn’t be BFFs in real life. While the Gossip Girl actress’s character is known for her designer wardrobe and flawless beauty, in real life, Meester couldn’t care less about keeping up with the trends or taming her tresses. “I’m not super OCD when it comes to every little flyaway,” Meester told PEOPLE. “I like being a little undone.”

And while the 24-year-old star recently became global spokeswoman for hair care brand Herbal Essences, she wouldn’t hesitate to chop off her signature long locks if for the right role. “I know it’s just hair and I can change it however I want. I haven’t shaved my head or anything like that.

But, you know if I needed to! It’s part of my job to change my hair.” For Meester, embracing change is part of her routine, admitting to “playing a part” when she’s on a red carpet. And she turns to her dream team, including makeup artist Chris Colbeck and hairstylist Charles Baker Strahan, to help create her image.

“It’s all about individuality and making a big statement. I leave it to the pros, they’re artists. I’ll be like, ‘just do your thing.’” For more on Meester’s style, hair hang ups and beauty saves and splurges, check out this week’s issue of PEOPLE, on newsstands now.
