Coloring can damage hair: in general, hair dyes contain chemicals that lift the scales of the hair fiber to allow the color to be absorbed. Too much coloring can therefore weaken the hair fiber. Less protected and more fragile, hair becomes damaged more quickly. It dries out more quickly and loses its shine and suppleness. On top of this, washing repeatedly and environmental aggressors (oxidation, sun, pollution, etc.) cause the color to lose its intensity and shine over time. The result is brittle, dry and dull hair.

Dull hair is caused by the breakdown of hair fibers. It raises the hair cuticles, which stops hair from reflecting as much light. Shiny hair is restored once those cuticles are closed.

To care for color-treated hair, the first step is to wash it gently so as not to dry out the lengths or remove the color pigments. Specially formulated for color-treated or dull hair, our SULFATE-FREE* Color Protective Shampoo gently washes hair to ensure that the color stays vibrant longer.
