Black to light brown hair with no yellow undertone
Hello!
I have dyed my med blond hair black for about 5 years. Recently I decided to go light brown. I went to hairdresser, we stripped the color out with color fix, they still were dark. Bleached abit,so they became light brown,but very yellow. Dyed light ash brown. The color changed, but it still was yellowish,which I didn't like. A few weeks later I've done the same again:stripper, it went med yellow blond, dyed another shade of light brown. Still the same result, with yellow undertone. Does anyone know how to get rid of this yellow undertone, to get nice brown shade? I was thinking of stripping again, then put toner on to neutralize yellow, and then dye the shade I want. Will toner actually help, or toners are used for blonde hair only?also, will the toner wash out, or it stays in like permanent color? I'm so lost cause hairdressers in my area seem to know nothing
Many thanks
