Redken Color Extend Conditioner is a daily conditioner for color-treated hair, built around cranberry seed oil and UVA/UVB filters that help protect color from fading. It's part of the original Color Extend line rather than the purple Blondage line, so it doesn't deposit toning pigment — it's meant purely to condition, smooth, and shield colored hair from sun and everyday wear.
It suits any color-treated hair type looking for daily upkeep after shampooing, adding shine and manageability while helping guard freshly-applied color. Redken designed it to follow Color Extend Shampoo as part of a daily routine.
