The Wella Professionals Ultimate Color Shampoo is a 1000 ml hair care product specifically designed for colored hair. This sulfate-free shampoo features a gentle cleansing system aimed at reducing color loss with each wash while maintaining color intensity. The formula includes glycine, pro vitamin B5 (panthenol), and a metal cleanser that work together to support color retention and provide a pleasant feeling on the scalp. With a pH-balanced composition that has been dermatologically tested, this vegan shampoo contains nourishing ingredients such as aloe barbadensis leaf juice, squalane, and lecithin to support hair structure. The formulation is free from sulfates and includes antioxidants like tocopherol and ascorbic acid to protect colored hair from environmental influences. The shampoo's cleansing system utilizes sodium cocoyl methyl isethionate, cocamidopropyl betaine, and sodium methyl oleoyl taurate for effective yet gentle cleansing without color washout. Additional components like allantoin and histidine contribute to the mild properties of the product, while citric acid and sodium citrate maintain optimal pH levels. The fragrance profile includes natural elements like citrus aurantium peel oil, complemented by notes of vanillin and coumarin. This professional shampoo represents a follow-up model in Wella's color care line, focusing on practical benefits for maintaining colored hair through regular use. The 1000 ml format allows for long-term use for consistent hair care routines.
