White On White is an extraordinary cleaning and subtle coloring in ZZn application. The small molecular colorant particles penetrate the upper layer of the hair (epidermis) to the bark without the use of harsh chemicals. White On White neutralises unwanted stains (which are not removed during cleaning) by issuing the necessary tones. The shampoo does not stain the outer layer of the hair surface and light is stimulated through the translucent hair surface what does the shine and colors enliven. White On White has a semi-permanent color that does not rely on hands or clothing. Due to its long shelf life of 4 weeks White On White truly unique! It can be used on all coat colors and all dog breeds.
