I use the JFM b/c my scalp has a reaction to stronger perms. The JFM seems to be gentler on my scalp. I do want my hair to be straight, which is why I want to use both. The length of my hair that has already been permed is under processed and is wavy when wet. My hairdresser wants to do a corrective and apply perm to the length of my hair. I haven't been back to her since she made that suggestion, and I am not sure if I will be back anytime soon. I figured if the Liquid keratin will relax a curl pattern without making it straight, then it should be able to relax hair that has already been relaxed with JFM texture softener. I just want to make sure my hair won't melt and/or fall out if I use both. I'll probably call the makers of both companies before I do anything to see if they foresee any problems, but I wanted the expert opinions of ladies here as well.
