Mother knows best!

In the November issue of Glamour, Nina Dobrev models a series of hairstyles for the fashion magazine. In real life, the 23-year-old Vampire Diaries star admits she's pretty conservative when it comes to changing up her look.

"My mom didn't start wearing makeup or hairspray until she was, like, 40. She's the least vain person ever," says Dobrev, who's dating costar Ian Somerhalder, 33. "When I became an actress, she said, 'I know they need your hair for this show, but you're going to need your hair for the rest of your life, so take care of it.' Since that day, I've been very diligent. I do hair masks multiple times a week, and I don't blow-dry it if I'm not working."

In one picture, Dobrev (wearing a Roland Mouret top and J.W Anderson brooch) rocks a messy, bouffant hairdo, which was accessorized with a Tarina Tarantino hairpin. In another, she sports sleek locks -- much like her Vampire Diaires alter-ego, Elena Gilbert. For Dobrev, who also plays vampire bad girl Katherine Pierce, it's important to modify her look with each character on the CW series. "Changing my hair helps me transform," she explains.

Dobrev (in Louis Vuitton) also models retro-inspired curls in Glamour, which she pinned to the side using Tarina Tarantino hair clips. Growing up in Canada, "Beauty wasn't something I spent a lot of time on," the actress admits. "Now I ask every hair and makeup artist I work with for tips. I'm in beauty school by association!"

The advice has certainly paid off. "Wash your face at the end of the night," the actress says. "There's nothing worse than sleeping in makeup. You wake up looking like a painting that's been left out in a rainstorm."
