i find an easy thing to do is to put a nice leave-in treatment spray or a tiny bit if its a creme through the midlengths-ends, then use an afrocomb and comb through. flip your head upside down and gently ruffle through your roots with a towel and gently squeeze through the ends, then let it dry naturally a little.
once its dryer, put it in a loose bun. then go to sleep (or if its morning, leave it in for 6-8 hours) and then take the bun out and thats about it. your hair will look different according to where you tie the bun (on top of head, middle or low)
play around with it.. its easy and effective.
