Hi .
I personally would reapply and develop visually.. Just out of interest..
Did you leave the colour on for the full development time? A Wella Trainer once told me to leave the tint for an hour and the tone will only deposit in the last ten mins..
I coloured a clients hair with wella 12/1 but the roots have gone quite brassy, what would anyone suggest to correct this??
I would appreciate any suggestions as I am really not happy with the result!
