Katiwei's recent post about business casual for women had me thinking about hair. What counts as business casual hair? I tend to air dry my hair, which means that it's got a frizzy halo. The top part of my hair is straight with a slight frizzy wave, whereas the underside has a stronger wave. As a result, it sort of looks messy, even when I brush it.

Is it expected that women with this kind of hair straighten their hair? Or tie it back if it's long? I imagine that if it's obviously curly, then a bit of gel suffices. For women of colour, I'm guessing that longer natural hair left loose is frowned upon, even though I wish that weren't the case.
