specific shampoo for Icy blond 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 which 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.
