growing graying hair out

I just went to get a "trim" on my hair I had been growing out to one length for over  a year, and I was butchered by the hairdresser! she apparantly did not like my long hair, and, although I asked her to only cut a couple of inches, she cut a tremendous amount in layers, and did it so quickly it was too late to do much about it....
Is there any way to take a hairdresser to small claims court? She did everything I asked her not too....and then just blew me off when I was upset.

also, I have mostly white hair ( prematurely) in the front, and salt and peper in the back that I dont like much...what is the most graceful way to grow this kind of hair long without frying it with chemicals and covering all the natural hair. I have been foiling.....any ideas

I am really grieving this hair "trim" a lot....and will just have to be much, much more cautious about who I let touch my hair in the future..

any support or advice would be helpful. With all these layers it will be quite a while before it will be grown out again, and she used thinning shears on the ends, which made it wispy, I am devistated...
