A shampoo formulated for professional use that prepares the hair for the subsequent technical service with Herbarius Dyes powder dyes. It deeply cleanses the hair and, thanks to its slightly alkaline pH, helps to open the cuticle scales, favouring the penetration of the product to be applied subsequently.
How to use
1 . Distribute over damp hair and gently massage the scalp with the palm of the hand and the lengths with the fingertips to prepare the hair to receive the subsequent treatment.
2 . Rinse.
3 . Repeat if necessary.
