The anti-metal agent present in CODE formula is called GLDA, Tetrasodium Glutamate DiAcetate. It is a naturally derived chelating agent made from renewable resouces. This plant-based molecule is a gentle alternative to synthetic chelators, able to blind tightly to metal ions and neutralises them.

HOW DOES IT WORK? As the hair is exposed to external agents (water, pollution, etc.), it starts accumulating metals. These metals, present in the hair, interact with the pigments during the colour service, modifying the colour outcome. This chelating agent binds with metals present in the hair, neutralising them and leaving a perfect, clean canvas ready to be coloured.

THE RESULTS: Improved reliability in achieving the desired final colour. Enhanced colour evenness.
