Question 1

Are brand equivalences exact?

Accepted Answer

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.

Question 2

Can I mix hair color from different brands?

Accepted Answer

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.

Question 3

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

Accepted Answer

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.

Question 4

Why does a 7.1 from one brand look different from another brand's 7.1?

Accepted Answer

Because the number indicates the manufacturer's intention, not an absolute result. The pigments, concentration, natural base, and technology of each brand produce slightly different results. A 7.1 will always be a medium ash blonde, but the exact intensity and undertone will vary.
