Bullfrog No-Yellow Enlightening Shampoo - Special shampoo against yellow colouring of light hair

The No-Yellow Enlightening Shampoo is a professional performance product designed for anyone with gray, white, or bleached hair and/or a beard that often tends to yellow over time. This product is capable of eliminating all traces of yellow thanks to the high concentration of blue pigments in its formula. The pigment can penetrate the hair and deposit itself within, where it interacts with and neutralizes the yellow pigmentation. This occurs because yellow and blue are complementary colors that tend to neutralize each other when combined. As a result, the shampoo gives hair and beard an extremely natural new radiance.
