Certain shampoos, like clarifying or dandruff-fighting formulas, can strip away hair color with sulfates and harsh chemicals. Get a color preserving shampoo, which is more gentle. We like the Joico K-Pak Color Therapy shampoo and conditioner, which forms a lightweight, protective shield over the hair shaftand smells great.
