Hey, I'm in need of advice... client has about 30% gray at root, level 5, color all over the place with bands of different colors as you can see, lots of orange on ends.. please help me figure out what formula to do for different sections cause I'm a little out of my depth here. She wants to be a medium to light ash brown like the pics below, or at least just tone down the orange. I would prefer to use Wella but if you have any recommendations. appreciate any suggestions.
