Review on Wella Color Tango 4NB Medium Neutral Brown Permanent Hair Color by Katie Miller

Let me start by saying that my hairstylist sister WARNED me not to buy this and I didn't listen. The color is far from the advertised color. I started with an ash blonde and a light shadow root. My intention was to turn the blonde into a grayer shade (hence the slate color). If you follow the instructions for the letter T, the end result is a DARK BROWN with a GREEN TINT - my hair is GREEN. I am disappointed and not at all satisfied with this product. Fair warning I didn't get the color I paid for.
