Specific shampoo for blonde hair Cleanses hair gently with a specific black pigment that counteracts yellow or orange tones in blond or lightened hair, giving ash tones. Use: Apply evenly over damp hair, leave in for a few minutes, then rinse. For a more intense result, leave in for a few minutes more. The icy blond products contain pigments that can give a very intense result on porous hair; once the desired result has been reached, alternate with a different shampoo to maintain the results. Proceed with icy blond conditioner.
