Terrible bangs and hair falling?

About 3 months ago my mom took me to this hair college to get my hair straightened permanently. The girl who did my hair but this one gel on my bangs to push them back and she put it on the top of my hair. My hair dryed up and started falling (I thing the girl put some weird drying gel on it). Almost all my long bangs fell out :( and now they are at a length of one inch which looks funny on my forehead. I don't want to have bangs and now I have to have them again thanks to this idiot that did my hair. How can I hide my bangs so it doesn't look like I have them? And how can I cancel out the straightening product and gel that made my hair dry? Please help!
