Hello! After two days of messing about with my hair, it looks like this, the top is a bit yellower than the ends, and after all of my toning attempts, the lengths are tinged purple in the middle. It's by no means the yellowest disaster I've ever seen, but of I were to stick on a metallic silver (probably live xxl) would it take? Would the bluer bits go bluer? What the hell can i do to rectify this shit show? Is my hair pale enough for a grey? Thanks!
You need to lighten the yellower bits if you want to even everything out. Popping a grey over everything will likely just highlight the uneveness more, as the lightest bits will stay lavender and you'll have a mix of greys and yellows elsewhere.
The yellow bits aren't light enough for the toner to take, since it only has a tiny amount of pigment. You'll either need to spot bleach those regions or do a darker fade into the lighter sections, which you can dilute a darker black dye and blend in a shadow root. I did something similar two colours ago, which you can see in my timeline. Either way, I'd highly recommend a strand test first.
