Hair color is categorised by Levels and Tones, to make choosing a shade easier to identify! “Levels” refer to how dark or light the shade is. Level 1 refers to Black while level 11 refers to Extra Light Blonde. Most permanent hair colors only lift your hair 2-3 levels, while bleach can lighten strands up to 7-8 levels. For the most natural look with less maintenance, it is important to stay within 2 levels of your natural hair color. The further you move away, the more dramatic your results will be, meaning your roots could be noticeable more quickly than if you had stayed closer to your natural hair color. Nutrisse, Olia, and Color Sensation are designed to lift your hair up to 2 levels so that you can go from a dark brown to a light brown or from a light brown to a blonde, for example, but not as far as a black to a blonde. For more dramatic change, look for our High Lift Brown shades or Blonde shades in Nutrisse Ultra Color, our highlighting kits, and our Platinum kits. Last but not least, before you buy your colour always check the box to make sure the shade will give you the result you’re looking for. There are pictures on the side of the box with before and after results. Match the shade at your roots (not your ends) to the “before” picture and you can expect a colour result shown on the after side. Another pro tip? Once you colour your hair, another box of hair dye will not lighten your hair without bleach, so make sure you’re committed to that Black or Dark Brown before you take the plunge! If you’re debating between two shades, it may be best to try the one that is slightly lighter so that if you do decide you want to go darker, you can reapply later.
