After using this product once, I was shocked when my brown hair turned a very brassy blonde color. It stripped it clean and I am extremely disappointed. I had to go back to my hairdresser to have her put in low lights and unfortunately, I can't find my receipt so I'm unable to return it to Harmon where I bought it. This has cost me a total of $90 to get my hair fixed and $10 for Shampoo that I want to throw away...
