Biolage Colorlast Deep Treatment Pack

No more cold-water rinses or skipping shampoos to stretch out color vibrancy. Immediately after using this treatment, hair is 3X stronger** with up to 70% less breakage*.

Small but mighty, each pack contains at least four applications. Easy to squeeze, our packs are 77% lighter than a container of the same size and perfectly sealed for a fresh application each time.

Pro Stylist Tip: No need to use conditioner, our highly concentrated formulas result in hair feeling more manageable and easier to detangle

*when used as a system with Biolage shampoo **vs. non-conditioning shampoo with the system of Shampoo and Mask
