From 8 weeks post until I relax, I do a ponytail rollerset, that helps with getting the newgrowth straight. Then I'll do a saran wrap treatment. Sometimes, I'll flat iron the indentions before doing the saran wrap treatment.
The same happened to me when I did a rollerset the regular way after 8 weeks post. Try doing a ponytail rollerset, where you section your hair off in several ponytails before rolling your hair.
In the beginning I blow out just the parts of the roots most visible, edges and such. After about 10 weeks or so I turn to the flat iron but I use it moreso to help the scarf out, not to get the roots bone straight. Overall, what really helps me is the tying down the hair with the scarf night after night after the wash.
