DSD De Luxe Violet Shampoo 4.1.1 - Violet Shampoo 4.1.1
Placental protein and vitamins enrich hair color. It neutralizes yellow tones in blonde and gray hair. Contains a rich blend of emollients, moisturizers, and color refreshers. Maintains and refreshes dull, ashy hair. Restores shine to hair and leaves no residue.
How the shampoo works: Purple and yellow are on opposite ends of the color spectrum. When you wash your hair with purple shampoo, the hair absorbs a small amount of purple pigment. Because they are opposites, purple neutralizes brassy yellow and restores the hair's lost beautiful color.
