@mwedzi, did you straighten your hair yourself? If so, what kind of products did you use and how long did it take? We have the same texture but every time I try to straighten, it starts reverting almost as soon as I left go of a section so I just give up and throw it into a bun.
The straightening itself took hardly any time at all. Maybe 45 minutes? I detangled and blow dried with a comb attachment, and that did most of the work. That took about 2 1/2 hours. I used some heat protectant generic stuff I got from Sally and a little coconut oil.
