Hair Color Disaster! HELP!!

I decided to trim my own hair condition and never go to a salon again, well 4 years later my hair is down to my bra line healthy and wavy. I studpidly went to a salon 1week ago to have some high and low lights put into make the color prettier. (Big mistake #2)

 

The salon is reputable and the colorist highlyl recommended, the low lights about a level 8 turned violet!! She was stunned and did not know what to do nor did her co-workers. I was shocked and horrified when I looked at my beautiful hair ruined.  She then proceeded to scrub, I mean scrub hard with clarifying shampoo twice still violet/ash. Then she decided to refoil the hair with high lift color Perfecta 900 still some violet and pink strips left.  The next day after I washed my hair 4x's during the night she refoiled my hair with high and low lights and it looked like mud the low lights bled into the high and just mismashed to together. Looked terrible still but at least the violet was gone.  The next day she put just the 900 highlights over the mud and it looks somewhat acceptable but not as nice as before I came into the salon.

 

My current problem is the aftermath of all that coloring my waves are straight won't hold curl, theres breakage and I have spent $150 on "the best"hair masks and crap and spend everyday trying to save my hair.  It is so porous, dry, frizzy and limp, I am stumped.  Should I put a clear coat glaze on it? What can I do to my poor ruffled cuticle I put moroccan hair oil and bought a better hair dryer thats supposedly professional and won't frizz ones hair as much and I use the cool setting and the disfuser it came with. The professional that did it states she can't do anymore for me and she's sorry.  Her hair is down to her butt, I bet she would be upset if it were done to her beautiful locks. Does frizzy hair heal?  what can I do to smooth it out?  I also have the Shades EQ clear coat, would that help?  Any one out there with information I would really appreciate it now.

Thank you!
