Thinking of Dyeing Your Hair? Keep It Nourished With These Moisturizing Products

Help maintain your strands' rich and shiny color with the Biolage ColorLast Shampoo ($24). Its gentle, low-pH formula doesn't strip color and instead helps prolong its tone and vibrancy — it's even suitable for non-color-treated hair. In honor of Earth Day, the brand is celebrating with a limited-edition bottle that's made of 100 percent recycled paper and plastic and 40 percent less plastic than traditional bottles. How cool is that?
