Damaged/Over Processed/Frizzy

A few months ago I colored/highlighted/re-colored all in the same day.  Needless to say, my hair was damaged.  My hairdresser gave me grief as she should have over it. 

Fast forward to now.  I wanted a change and I was letting my short hair grow, and was at an awkward stage.

My hair dresser recommended I get a Tizzy Perm and she used the biggest rods she had.  When she took the rods out, I hated it because I felt like I looked like a white woman with a jerry curl.  I told her to cut it all out and that I would go back short.  Another hairdresser there said that I could straighten it back right then.  So that's what we did.  We ran another perm solution through it but combed it through.

My hair is so very dry, and when I dry it with the dryer it is so frizzy.  I have done a deep ION conditioner, a hot oil treatment, leave in conditioners, and I have even slept in the ION conditioner.  Nothing seems to be helping it.

What can I do to get my once healthy soft hair back?  Oh and my roots need to be done very badly, so that's another process that needs to be done.

Thanks.
