Have you tried the curly girl (CG) method? Here's a great link describing it: The College Curly
I would recommend trying this, give your hair lots of TLC and time to recover, and you will soon have the curls you want!
Not sure if you've found this thread, but it is what started me on my CG journey. Post your before & After CG pics
It took me awhile to get the hang of everything, but now I am loving my hair, for the first time in my life.
