Find out what the number on the Salonist hair color box can tell you about how the shade inside will look with an explanation from Vidal Sassoon Atelier Colourist Stuart Ross.
The numbers on the boxes are the shade and tone of the hair color. The number before the slash indicates the level of the color, or how light or dark the shade is, with 1 being the darkest, black, and 10 being the lightest, blonde. The number after the slash represents the tone, or how warm or cool the shade is. 1s are cooler, 3s are warmer and 0s are neutral. So a 5/3 is medium brown hair color, warm, with gold tones.
A superscript means it’s an intense or vibrant shade. For example, the 5/45 2 Medium Intense Red is a medium brown level 5, but with red and mahogany tones.
