I think confidence is sexy - it's not about what you look like or what you do or don't do with your hair/face/fashion. Be unashamedly confident in whatever look you choose to rock and THAT will rock someone's world.
That being said, Coco Chanel said there are no ugly women, just lazy ones. I think that when you choose to go 'natural' you should still be very well 'groomed'!
