Wellas mixing ratios are 1:1.5 or 1:2 for blondor. I prefer 1:2 on scalp, it doesn't tend to dry out as much. You should lift the hair to palest yellow (10) and then tone to white/platinum. If you lift the hair to white you risk hydralising the hair, braking the bonds, which will cause it to snap off.Hello! Is it ok to use 1:1 blondor with 6% on scalp to get platinum white blonde? Thank you!
