Colour advice

Hi all

If I wanted to do purple lowlights on a client with very dark almost black virgin hair, what % peroxide would I mix with it. I have just qualified so I want to be sure.
Thanks

i think 20vol would be alright, do a strand test just to see?

20 vol for subtle, 30 vol if you want pop. The extra level of lift will add brightness to the shade of purple.

Thanks for all your help. (I don't know what I would do without this forum!)
