I washed in the mornings when my hair was short (or even just shorter) but it takes too much time to air dry now. I prefer to wash it at night, when I have more leisure time. I also get good results from flipping damp hair over a pillow and sleeping (aka pillow plopping). It takes the weight off the hair so I wake up with nice curl formation instead of the stretched-out waves I get from air drying with it all hanging down.
3a/b, fine, lots of it
