How to Care for Colored Hair
1. Stick to Sulfate-Free Shampoo
Sodium lauryl sulfate and sodium laureth sulfate are two common chemicals used as cleaning agents in shampoo. The sudsy lather dissolves dirt and oily residue, but it can also be abrasive. The friction from scrubbing it into your scalp can cause hair cuticles to open and the color to seep out. To prevent fading, use sulfate-free shampoos specifically formulated for color-treated locks. Antioxidants and amino acids should be on the list of active ingredients.
