You’ve never colored your hair, or if it’s been longer than 6 months, we recommend you lighten or darken your natural within 2 levels.
So if you have medium brown hair (level 5), you can darken to a deep rich brown (level 3), or lighten to a sunnier dark blonde (level 7) – but we usually don’t recommend going lighter than 2 levels with at-home color, because the results can get brassy.
If your hair is currently colored darker than your natural shade, you have to be careful to avoid off-tones. You can still go up to 2 levels darker, but we would recommend you only take your hair 1 level lighter.
We recommend only going 2 levels darker, whether or not you’ve colored before. You can go darker than 2 levels, but it will be very difficult to lighten in the future.
Each box of color has a name and number on it that will help you understand more about the shade you’re selecting.
The number before the slash indicates the level of hair color, with 1 being the darkest (black), and 10 being the lightest (blonde).
The number or numbers after the slash indicates the tone. 1s are cooler, 3s are warmer, and 0s are neutral. A superscript means you have an intense shade.
