Can anyone recommend some formulas?? Level 6 ash, using redken shades to shadow root! Applying to covet & mane, 613/18A!

Just remember that extensions take ashier. So I always use 6n/6gb and it turns ashy. Or just n if you want even ashier

I’m worried that doing a level six ash on that light of a blonde isn’t going to take very well😕 I would probably fill it to a level seven first then apply a permanent 6-0/7-1 over the top.
