Hi, so recently my hair has passed the point of no return, i’ve bleached the ends about 8+ times (white blonde then brown then white again) I don’t understand how I am not bald, they’re now icy blonde. My roots growth (from roots to ears) is not over processed as I’ve only bleached it twice, it is yellow blonde. I stopped bleaching the roots with fear that I would touch the ends bc I know they’ll fall out. So the only thing Im doing for now is putting direct dyes on my hair to make the color somewhat uniform, however I bought a rose gold dye I thought was direct application but needs to be mixed with a 10vol developer . Can I put 10 vol developer over my over processed hair?
with a toner yes, you can also mix it with a mask or conditionner, which will also dilute it a bit.
I'm not sure if you've already done it, but I'd just strand test. It depends on the toner, as some are harsher than others. Peroxide is also inherently a bit drying, so it may cause issues if your hair is very on the edge.
i would not do it, i would return it if you can and mix up a rose gold with direct dye, some toners have amonia and peroxide and if you hair is damaged then the last thing you need is a toner with those ingredients
