I've been getting blonde highlights for years now. I went to a new salon to get my roots touched up, which grew out to about 3 inches. The highlights turned out terribly bright and the lowlights too dark. In the end I told her to put an ash toner over it to even it out. I hated it because it turned out too dark. A month later I went to another salon and got a clarifying treatment to remove some of the dark toner and put on a different toner to make it lighter. It's still nowhere near how light I want it to be. What can I do?
