Equivalences across 21 brands

Level 10 Ash (/1)

Q: Are brand equivalences exact?

Level and reflect equivalences are a useful reference, but not identical. Each brand has its own chemical formulation, pigments and technology. Two "equivalent" codes will produce similar but not identical results. Factors like natural base, porosity and color history affect the final outcome.

Q: Can I switch brands and keep the same color?

Generally yes. If you maintain the same level and reflect, the result will be very similar. However, a strand test is recommended when switching brands for the first time, as formulation differences can produce slightly different nuances.

Professional colorimetry

Level 10 Ash: what it means

Level 10 corresponds to a lightest blonde on the universal colorimetry scale (1 = black, 10 = lightest blonde). It measures the lightness or darkness of hair, independent of the reflect.

The ash (.1) reflect adds a cool, gray-blue undertone that neutralizes warmth. It is the most requested reflect for counteracting orange or yellow tones. Ideal for those who prefer a cool, sophisticated result without visible warmth.

Each brand codes level and reflect differently. The table above shows how the major professional brands name this same shade: level 10, ash reflect.
