This professional-grade shampoo by Ref Stockholm is specifically formulated to enhance and preserve the vibrancy of colored hair. It features a nourishing blend of Organic Acai Oil and Quinoa Protein. Organic Acai Oil helps deliver potent antioxidants, protecting the hair structure from environmental aggressors that can lead to premature color fading. Quinoa Protein penetrates the hair shaft to strengthen integrity and improve moisture retention, resulting in smoother, more resilient strands. Ideal for maintaining salon-fresh color results between washes, this shampoo gently cleanses without stripping essential moisture or tone from highlighted or dyed hair.
