Experts Reveal Their Favorite Products For Maintaining Rich (and Healthy!) Brunette Color

"What I really like about this product is that it's ammonia-free and can cover grays. Colorsilk is formulated with UV defense that helps keep the color from fading and adds shine. It's also important to use a good color-treatment shampoo. (I recommend Bumble and Bumble's Color Minded Sulfate Free Shampoo ($31), which resurfaces the damaged cuticle and helps prevent the color from fading.)" — Cassandra Kaeding
