Creamy Crack

OK, so here is my relaxed hair. I have been on the creamy crack for about 10 years. This picture so the longest my hair has gotten being relaxed. You can't tell from this picture, but my hair is very thin. As a child it was very thick. I want the thickness back. I feel like I do not have anything to loose by going natural. I can press my hair or flat iron it straight if I want and still have my natural coif. With my relaxer, I can't get the natural coil back
