Natural hair ladies: did you press/flat iron your natural hair during transitioning to natural?

I have started my relaxer stretch and am only 7 weeks post, but to me, that's good because most of the time my hair really needs a perm within 5 weeks. I have been doing a lot of research, have the best products I could get. Right now I use creme of nature and ORS deep conditioning when I do the deep conditioning, and I do hot oil treatments. Now I know there are a lot of opinions on heat and all of that, but my hair does not look right air dry so I do blow out my roots but I have it on low heat and low airway. I make sure I use a serum and heat protectant, and today I'm going to get the ends of my hair clipped. But does anybody have any experience when it comes to pressing/flat ironing you hair to match the relaxed? Have you done it? What were the results. Hairdressers do recommend this to people, and some say that they had no problem with it. I just need my own opinions and advice. I'm not growing it out to have a fro. I still want the straight look, but I am really tired of relaxers and I'm trying to take care of my hair bettter. Also, any good recommendations of leave-in conditioners/detanglers. The African Royal made my scalp itch so right now I am using Just for Me leave-in. (sorry for all the questions) :(
