What does the shade number 7.31 mean and will it match my current hair color?

The number 7.31 follows the international color level system: 7 indicates the depth (dark blonde), 3 is the primary tone (gold/warm), and 1 is the secondary tone (ash/cool). This combination aims for a dark blonde that balances warmth with a muted, polished finish rather than a brassy gold result.

Because this is a permanent oxidative dye, the final shade depends heavily on your natural or previously colored base. On natural dark blonde to light brown hair (levels 6–7), you’ll see the truest 7.31 result. On lighter bases it may appear brighter and more golden; on darker bases (level 5 or below) it will not lighten significantly — permanent color lifts only 1–2 levels at most — so the result will be a subtle tonal shift rather than a full shade change.

If your hair has been previously colored, the dye will deposit tone but cannot lift artificial pigment. Porous or damaged ends absorb more pigment and can turn cooler or darker; the included keratin balm helps even out porosity after rinsing. For a precise match, do a strand test on a hidden section using the exact mixing ratio and timing you plan for the full application.
