Common questions when converting between these brands

How many The Color shades have an exact equivalent in INOA?

Of the 21 The Color shades, 20 have an exact equivalent in INOA, 1 approximate. The level (1-10) is universal; what varies is the reflect.

Are brand equivalences exact?

No. Equivalences are approximate because each brand uses different pigments, bases, and concentrations. The level (1-10) is universal, but the reflect result may vary. We always recommend doing a strand test when switching brands.

Can I mix hair color from different brands?

It's not recommended. Each brand formulates its products with specific chemistry (pH, alkalizing agent, pigment system). Mixing brands can create unpredictable reactions and unwanted results. Always use color and developer from the same brand.

What if the exact shade doesn't exist in the other brand?

The tool shows you the closest available shade. If you need a very specific result, you can combine two shades from the target brand (for example, mixing a natural with an ash to get a soft ash). Blendsor calculates these mixes automatically.
