Wow all of these people saying it takes them no time at all!
I have naturally curly hair . . . which means nothing is easy (unless you're a guy with short hair). Just brushing it out takes around ten minutes alone. Now if I fix my hair blow drying takes around thirty minutes for me (I use a diffusor, and my hair is just very long), if I use a curling iron it takes me an hour, and if I use a hair straightener it takes an hour. If I let it air dry it takes a while too, but some mornings I'll braid it and that takes just a few minutes, and if I tie it into a little side pony tail that takes a few seconds.
Anywhere from 2 to 30 minutes - the maximum is including blow-drying and straightening it.
But sometimes (like, the last three-ish weeks) I wish I could either wear a wig or a head covering to hide my hair completely. Why did I have to try trimming my own bangs?! :( My hair is one of my very few prides so I was quite angry at myself for cutting them too short.
Most days it's a quick brush and go; I'd say conservatively, 10 seconds. If I have to blow it dry and curl it, maybe 15 minutes. Less when it's a s short as it is right now, since I finally got it cut.
