When dealing with white hair the only way to completely remove discoloration is usually bleach, but since bleach and/or peroxide damages the canines coat permanently (or should we say until it falls out) we do not want to be bleaching. Instead we are going to the other end of the color spectrum and depositing pigment, drabbing yellow. What we are drabbing yellow with is 37 different color pigments and due to White On White's molecular structure being so tinny, we are able to remove discoloration under the cuticle lens and deposit pigment in one application without opening the cuticle lens through bleach, but depositing through the cracks and crevices. Example: The diminutive molecular structure of all of Chris Christensen Systems treatments are like White On White being the golf ball versus a basketball, the molecular structure of Chris Christensen systems treatments are so tiny that they can go under the cuticle lens and clean and deposit pigment without the use of harsh chemicals like bleach and peroxide. The long term effects of using products with bleach or peroxide are detrimental and irreversible and you also do not want to use dyes for they do not go under the cuticle lens, dyes lay on top of the lens therefore dulling the coat in appearance and also rubbing off on Judges hands.
