Product story

4D Color Experts was developed to combine colour intensity with hair fibre protection during chemical processing. The four dimensions in its name are depth, shine, coverage and care. The formula is designed to deliver precise shades while caring for the hair fibre as the colour develops.

Alongside natural base shades, the shade chart includes cool and enhanced-coverage options, ash and pearl tones, and gold, copper, red, violet and brown shades. High-lift colours and correctors form separate groups. These families let colourists select both the depth of colour and the desired undertone.

For grey coverage, the ratio of base shade to chosen shade is adjusted to the proportion of grey hair. Toning, standard permanent colouring and high-lift colouring each have different mixing ratios and processing times. This allows colours from one palette to meet a range of professional colouring needs, following the appropriate technical instructions for each service.
