Once I'm 6 weeks post I don't go for the sleek look all the time.. I can blow dry and do the scarf method after a wash and that works well enough but since I don't want to have heat in my hair constantly I don't rely on that method. The scarf method alone does work for me somewhat but I'm usually too lazy to think about it and I don't like wearing a scarf to bed on a regular basis cause they stress my edges.
Have you considered alternate hairstyles that take advantage of the thickness/body your new growth adds? Like braid-outs, twist-outs, bantu-knot outs etc. They're easy to work with and hard to get wrong IMO, plus they stretch out your roots a bit.
Take a look at this thread, maybe you'll get some inspiration:
Relaxed hair means straight hair ALL the time.....Um, NOT!!
