Redken Color Extend to optimize the different colors, Redken has researched which techniques and nutrients are needed for your hair. Based on this research, a whole range of products has been developed to nourish a natural color, but also dyed hair and to bring out the best in your hair color.

The different hair colors have different problems when it comes to optimizing the color. Gray, blond and brown hair with highlights are affected by the sun and therefore take on a yellowish undertone. You can't all use the same product for this, because this also changes your base color. Redken Color Extend therefore has different series that focus on the different (dyed) hair colors.
