Hey everyone!
I am looking for some advice on toning my hair. At the minute it is dark brown and copper ombré. I want to take some of the brassiness out of the copper and was wondering if it would be ok to mix the p01 with 40vol? It's just I used both 10 and 20vol in the past and they didn't make much of a difference! I'm just not sure what effect 40vol would have on my hair and would love some advice so I don't end up with a hair disaster!! Thanks in advance
