In 2013, Refinery 29 named Color Wow Color Security Shampoo as one of the best sulfate-free shampoos for hair that has been color-treated. The product claims to prolong the color treatment and moisturize the tresses.
Refinery 29 recommended Goldwell Dualsenses Green True Color sulfate-free shampoo as well. The shampoo preserves hair color and is rich in vitamins. Dualsenses Green True Color also gives the hair shine and protects it from free radicals.
Refinery 29 also recommended Black Vanilla Moisturizing sulfate-free shampoo from Carol's Daughter. The shampoo contains aloe leaf juice, which moisturizes the hair. This product claims to make hair very soft, and it has a distinct vanilla scent.
