Matrix Mega Smooth Professional Shampooo gently cleanses and nourishes chemically-treated hair, particularly straightened hair. Infused with vitamins A and E, essential fatty acids, and shea butter, it reduces frizz, protects against environmental aggressors, and increases moisture retention. Matrix Mega Smooth Professional Shampoo ensures smooth, shiny hair with improved manageability, making it an ideal choice for maintaining straightened hair post-salon.
