Oprah DOES have the power to wear her hair anyway she wants. Which is why it would be great to see her with her natural hair once in awhile, in addition to her wigs and such (which I happen to like also). If more people in the industry were seen with their natural hair, maybe the whole "you have bad hair, your hair isn't good enough, you need to straighten that hair if you want to work here" statements would be a thing of the past.
I don't mean people like Oprah shouldn't wear their hair (or clothes or anythings else) however they want. They certainly should. But I think most people in that industry and others are TOLD how to wear their hair, it's not their choice.
People with Oprah's power could help change that.
