While Sammi Sweetheart is known for being “obsessed” with keeping her long hair super straight, lately she’s been trying out different styles and even going natural for the camera, showing off the beautiful, curly texture in her hair.

We’ve seen Deena Nicole rock a ton of different hairstyles since we first met her on Season 3 of Jersey Shore, including curly, wavy, straight, red, blonde, blonde streaks, and super-long! Even though she had a few hair mishaps on the show — remember when JWOWW had to yank out her extensions in Italy?! — she’s planning on going to beauty school soon to learn to be an awesome hair stylist and hopefully won’t have any more hair fiascos.

Recently, Sammi and Deena posted gorgeous pics of themselves to Instagram, wearing their beautiful long brown hair sleek and straight. But who rocked the look better?

Deena Instagrammed a shot of her in the car, wearing St. Paddy’s Day green for “all [her] Irish peeps.” She looks beautiful in a bright green jacket and simple makeup that makes her lips look lovely and naturally big brown eyes pop.

Sammi also Instagrammed a pic in celebration of a “Happy Wednesday!”, showing off her Photoshop skills by splitting the pic down the middle in two identical self-portraits, one in color and one in black-and-white. She looks gorgeous in a pretty white top and her signature Sammi grin, her sleek straight hair parted at the side to give it a natural lift.

Both girls look stunning in their selfies, but it’s up to you to decide who rocks the sleek, straight-haired look better! Vote below.
