12/81 & 12/61 = 12% Koleston Perfect

Could you please tell me how Kadus toners work? What developer to use and what ratios? Many thanks. There isn't really a lot of info on this brand..

It's exactly the same as wella. So the demi range is mixed 1:2 with 1.9%. Apply to towel dried hair and leave for up to 20mins
