That depends on how you look at it.
Shower: 15 minutes. Styling/Dressing/Makeup: Probably the same...
But it takes about 90 minutes for my hair to dry. I can't blow dry if I want it to look decent - and trust me, I've tried diffusers and cool settings and all the other suggestions. It has to air dry. And since it's curly, I can't wash it the night before, it has to be the same day. I usually take my shower about 2 hours before I have to leave, then spend an hour or so doing dishes, playing on the internet, etc., then I finish getting ready.
