The range is available in four different shades: Silver, Dove Grey, Slate Grey and Grey Lilac. The transparent effect brings out the natural silver sheen, and grows out virtually seamlessly at the hairline. At the same time, the siliamine and collagen complex builds up the hair, restoring its youthful freshness. Schwarzkopf Professional offers two different in-salon treatments to beautify white hair. For Professional Use only. Net wt. 60 ml / 2.0 fl. oz. Turn yellowish, matte hair into a silky, shining silver, which lasts for up to twenty-five washes. It emphasizes the beauty of your natural hair color, and quickly perfects customer’s personal shade of silver. Tonal Refining - For customers who want an even softer end result, Schwarzkopf Professional offers a second application. Silver added to customer’s Tonal Refiner reduces the intensity of the shade, and gives a soft silver sheen in twenty minutes. Refining Treatment - Enhance the natural shade of white with a subtle silver sheen, for a soft and delicate result. The additional care treatment combined with color enhancement, takes ten minutes.
