Spring Fever, I too had a hair disaster once ... I had a beautiful head of long hair in great condition, I'd been growing it my whole life. I was in college and had always wanted beautiful *curly* hair, so I went to a friend's cousin and got a perm. She left it on for a long time since it was "virgin" hair. When she unrolled one of the rods to take a look, suddenly she and one of the others were dragging me to the sink, unrolling the rods feverishly, and rinsing. It turns out that my hair takes an excellent perm and by leaving it on so long she had irreparably damaged my hair. She also must've applied the solution unevenly because (even after she whacked at it) the hair on one side of my head was 6 inches longer than on the other side. Had I known anything, I'd have gone home and washed my hair but good, and kept doing it, but I didn't. Eventually I had to face reality and have all of it cut off.
The good news was that I liked it short--so much easier to take care of.
As far as your disaster--DO NOT TRY TO FIX THIS AT HOME. You don't like the orange? It could turn green, and I am not kidding. The others who've said you need a primo color expert who comes highly recommended (by multiple reliable sources, I might add) are absolutely right! Put on a baseball cap (you could have one custom-embroidered "Bad Hair Day," I had one made for a boyfriend
), and go about your business till you can get an appt with someone who can fix this.
And it's true about the cap--that's very 1970s old school. I had highlights done that way nearly 20 years ago now, and it was old school then.
I bet something good will come of this--you're going to have better color when this is all over--and you may also learn to appreciate your hair au naturel, as I did
I haven't had a perm in many moons now.
And perhaps your erstwhile hairstylist will go get some training
PS I'm pretty adventurous with my hair & always tell myself, "The great thing about hair is it always grows out."
