Chemically Straightened hair??

Ok for my dance in december I got my hair done and it was very soft and beautiful I'd always get compliments on it and very flexible. I got a "Motions" relaxer from causcasian ladies and they claimed they could do ethnic hair and went on about it while doing my hair. They put it in and washed it out but not good enough. Most of my hair fell out and I have really low self esteem now its like WOW how'd I got from THIS to this..? My front edge layers are gone and my second layers and several layers are really thinned out and its lots of breakage and unhealthiness in the front but really healthy looking and flexible in the back. My hair is shorter and just horrible to me. Now I've just decided to wear my hair pulled back and mousse'd down on the edges into a pony tail and etc. It's gonna grow back over the summer obviously but anyway to speed up the process or make it better with any anti-breakage products? Like hair growth and thickening products and all that?
