When you put in the time, effort, and money to dye your hair, you want to make sure it won't fade as soon as you wash it. The key is to look for a shampoo that says it's sulfate-free. Sulfate can strip your hair of its new color, plus cause frizz. Note that without sulfates, the shampoo won't produce suds, which takes some getting used to when you love the bubbles, but that doesn't mean your hair isn't getting just as clean.
