Hi, can anyone help me please. My hair is medium brown and I would say I’m about 80% grey. Im allergic to PPD. My hairdresser said she can start putting some bleach foils in my hair but it will take some time because I’m dark. Does anyone know of a toner I can use that will take the brassiness out but will not effect the brown that’s still in my hair. I’m not ready to completely transition to grey I’m only 40 but I’m willing to go lighter just don’t know what my options are
