Have any questions about Four Reasons?

Color Mask Treatments are pigmented deep conditioners, and Color Mask Shampoos are pigmented shampoos.

Color Masks are specially formulated for color-treated hair, as they perfectly
take into account all that colored hair needs: color refresh and deep

Color Masks don't contain harsh chemicals like ammonia. Quite the contrary
actually! They gently cleanse and deeply condition and repair hair, while
depositing color pigments to the hair's surface.

Color Masks are intended to tone hair or maintain your existing hair color. We all know that beautiful hair color can fade and lose its vibrancy within a few washes. That's where Color Masks come in! Use in place of regular shampoo or conditioner whenever your hair color needs to be refreshed. Simple as that!
