Do not mix hair colorants from different brands or lines

Similar-looking shades do not mean the formulas or reaction systems are compatible.

01

What mixing can change

Colorants, oxidation systems, pH and ratios may differ. Unapproved mixing can create unpredictable color, irritation or hair damage.

02

Use the specified tools

Use the container and tools supplied or permitted by the instructions. Do not substitute metal utensils or add old mixture to a new product.

03

If you want a custom tone

Choose shades or combinations the brand explicitly supports. If the product provides no mixing guidance, do not follow an improvised online formula.
