Oprah Goes All Natural on Twitter, 'O' Cover

It's rare celebrities leave their hair and makeup products behind, but this month Oprah Winfrey is doing it twice.

Former talk show host Oprah Winfrey posted a photo to her Instagram of herself wearing glasses, without makeup and showing off her many wigs. The OWN network CEO is currently filming 'The Butler' directed by Lee Daniels in New Orleans and the wigs are for her character Gloria Gaines.

"Me and my "girls " in the makeup trailer," the media mogul tweeted alongside the photo.

It's rare Winfrey, 58, is seen au natural but the talk show host will appear on the September cover of her magazine, O, au natural.

"For the first time ever, Oprah's appearing on the cover of O without blow-drying or straightening her hair," a statement on Winfrey's website said. "She says that wearing her hair naturally-as she often does on weekends and on vacation-makes her feel unencumbered. But there was a time when she wanted to just cut it all off.

"I wanted to wear it close-cropped a la Camille Cosby but her husband Bill convinced me otherwise. 'Don't do it,' he said. 'You've got the wrong head shape and you'll disappoint yourself.' I took his advice," she says. Although, never one to shy away from a style update, Winfrey is a firm believer that changing your hairstyle can change what we see and feel is possible. "I even notice a change in my dogs when they get their summer cuts: they're friskier and livelier, feeling more themselves once the weight of the hair is released."

Winfrey has sported many hairstyles over the years from straight bobs to Snooki-esque bumps. But she's faced criticism for not embracing curly hair. Four years ago, website Naturally Curly, wrote a letter to the star sharing their disappointment in her Great American Haircut Makeover show which straightened girls' naturally curly locks.

"Oprah, you are well loved the world over, due in no small part to your uplifting gospel of self-acceptance. Yet, in the eyes of curlies, these makeovers send an unmistakable - and most disheartening - message that one's natural hair isn't acceptable. These makeovers suggest that in order to be beautiful, one must completely alter one's appearance into something not at all natural," the letter stated.

The September issue of O hits newsstands Aug. 7.
