Hi there, I need some help when dying my hair a dark Sliver. I currently have orange/red hair and I plan to bleach this out in the next month to go a sliver/grey colour. Once I have done this I was thinking about using Koleston perfect 0/11 intense ash, would this work on a dark blonde or does anyone recommend any grey/ sliver toners? I have experience with using wella toners before but I used a very light sliver as my hair was lightest blonde I would love peoples recommendations and help with this Thank you!!
