How can i bring my fried hair back to life?

Ok, my hair has been died numerous amount of times, its had a perm, and its just awful. I use to straighten it EVERYDAY and also blow dry it and curl it and all kinds of stuff. And now, my hair is pretty much dead and i hate it. Also, when i shower, my hair dries really fast and gets all stiff. I have been using Aussies Deeeep Conditioner and its helped alot and i started taking pre-natal vitamins for it and i use Suave Professionals Shampoo and Conditioner (Compared to Aveda) and all that seems to be helping it a little... Is there anything i can do to get it healthier faster? and make it grow faster?
