Just a quick question.... If hair is bleached colour touch 1.9 should be used only?
4% will just over darken...
It will depend on what you are using it for, if on blonde, (like your other lady) 1.9% will be better, its like we all know 3% is 10vol which in most cases is same shade or darker, so wellas 4% is staying same base or darker, 1.9% is deposit only, so say you have a lady want brown, returns for roots and wants ends refreshed, 4% would be better in this case on the ends. If you are toning 1.9% is better.
It's been a while since I have used wella so I could be wrong, but its like joico have a note with their toners: for maximum deposit use glaze (1.5%), for medium deposit use 3% (10vol) and for minimum deposit use 6% (20vol)
