I have been a self-relaxer for many years. Well, in December 2005 (before I found hairboards), I decided that the back of my hair was "resistant," and I needed to let the relaxer marinade on that section a little longer.....like 15 minutes longer, for a total of 30 minutes! (My total process--application and smoothing--takes only 15 minutes.) To make matters worse, I had even pulled the relaxer down the length of my hair to the ends, with no protective barrier (conditioner, oil, etc.) on my ends. When I finally rinsed the relaxer out, the nape was basically gone, and I had breakage throughout the back section...pieces as long as 3-4" long had just broken off. After the damage, my hair was barely shoulder length.
As a result, I began to regularly moisturize that section and stopped using all direct heat. Six months later, I found hairboards and now my hair is thick, healthy and brastrap. I still self-relax (texlax) and have a much better understanding of what I am doing now. My nape is growing back nicely as well.
