Why Do My Roots Go Lighter When I Dye My Hair?
When you dye your hair, especially if you are going lighter, the chemicals in the hair dye strip away natural pigments from your hair. Because the hair at your roots is newer, it has less pigment than the rest of your hair. As a result, it takes less time for the chemicals to strip away the pigment from the hair at your roots, making it appear lighter than the rest of your hair. This is why it’s important to touch up your roots regularly to maintain the same color throughout your hair.
