Jessie J shaves her head for charity.

Last night Jessie J shaved her hair for charity and instagrammed this picture straight after doing so. Isn't it fascinating how shocking a bald woman still is, so much so that it instantly filled my twitter timeline in a way that nothing else on television did last night.

Jessie J is stunning, and remains stunning with no hair. Despite having an ace face, I still think it's a pretty brave thing to do. Femininity is still so closely linked to our hair, and the dream of long hair is still the pinacle of sexiness for many (most women in my hair salon want to grow their hair longer).

I'm pretty darn sure I could never shave my head voluntarily, which raises some questions about what a true sense of self and beauty actually means.

I wonder if Jessie will cover her head, or rock it?
