Understanding Professional Hair Color Numbering Systems

Learning about the hair color numbering system helps you choose the right hair color. It’s a detailed code that lets stylists get exact shades and talk clearly with clients.
How Hair Color Numbers Work
The system uses numbers from 0 (darkest black) to 12 (lightest blonde). The first number shows the main color or color level. The second number often points to undertones or highlights.
For example, “8.2” means the color is light blonde (8) with a hint of violet or ash (.2). This adds depth to the main color.
Decoding Color Levels and Undertones
Color levels go from 1 (black) to 12 (lightest blonde). Knowing these levels is key to getting the right shade. Undertones can be warm (golden, red), cool (ash, violet), or neutral.
Knowing the hair color system lets you tell stylists what you want. This way, you get a color that makes you happy.
