Recently, I went to a Salon to have my hair changed back to it's natural color. Big Surprise, it came out too dark. My hair is as dark as Katherine McPhees, but I have light blue eyes and fair skin, so this looks awful. I asked for a medium brown and came out with a dark brown. I didn't want to tell the guy I hated it, for fear that he would make it worse.

I have contacted another salon to have this corrected. Has anyone had any experience with this process? I am willing to pay to have it fixed right, but want to know if this truly makes it better?

Yes, you should go to another salon and have them fix your hair. There are a lot of good hairstylists out there that may be able to correct the problem for you. Remember to communicate with the hairstylist to make sure that you get the color you want.

Today I am about to get that very question answered as I made a big mistake yesterday bu dying my blonde hair dark brown (the hair stylist called it "caramel"). Of course, my natural hair color is not blonde, its turned to a dirty blonde at this point and I was just so sick of having roots that I couldn't take it anymore so I decided to answer the question I've always had which is: "would i look better brunette?". NO NO NO. I look like a fool.
But I am calling the salon to have them fix it today.. hopefully they do it.
Ill keep you posted.
