Hello,
I'm currently abroad for several months and I can't order any 10vol developer here. All I have is 20vol. I want to use it together with wella koleston 9/8 to reduce the yellow and orange tones in my freshly bleached hair (it's currently level 8-10 but I'll go over the ends again, hopefully reaching 9 everywhere).
Now, is there anything I could add to the mixture to reduce the 20 vol intensity a bit without it messing with the colour?
Conditioner, coconut oil, water?
