I have treated my hair with bleach and a high lift color. My hair is sooooo white with a yellow tone that I want to tone it down A LOT by adding a darker blonde toner. Will adding the toner to my already damaged hair damage it more?

Also, any ideas as to what is a good toner/color to use?


Would adding a filler before I tone it darker help maintain it?

Yes, you should pre pigment the hair by using a filler before applying the darker shade and to avoid unwanted tones.
What kind of blonde shade were you looking for? Ash? Gold?
