Hello,
I’m going to colour my hair from a dark brown to a (hopefully) pale ashy slightly violet blonde.
I’ve bleached it before and managed to get it very light so should be ok with that part but it was a while ago so I was wondering if this would be correct:
A) bleach with 20 vol developer once or maybe twice
B) Followed by either Wella t18 toner OR Wella koleston perfect in 10/16 again using 20 vol developer?
If any hairdressers could advise I’d be so grateful, thank you!
