If you don't mind me asking, what's your regimen if you have one at all? Do you use a lot of heat? Do you deep condition? Is the root of your problem the relaxer itself, or is your practices ON TOP of the relaxer? That'll help you decide the next steps you should take.
I only use heat when I dry my hair (using a heat protector) I DC once a week. I alternate between protein and moisture, and then use Aphogee Pro Vitamin leave in conditioner, ORS Olive Oil Hair Moisturizing Lotion and recently started using JBCO. I tend to wrap my hair. Today I twisted my own hair and plan to keep this in for a week or two.

I have also been told that the breakage could be due to stress. I lost a close relative just before I started to relax last year and have been feeling very down and also lost a lot of weight due to loss of appetite. My appetite has now come back. I guess maybe I should have waited a while before relaxing as my body has been under a lot of stress over the past few month due to grieving.
