Usage It starts with good preparation: Take your time and have the following tools ready: a protective cape or an old towel, disposable gloves, hair clips, and a timer so you don’t forget the exposure time. Coloring: EXCELLENCE products are easy to use: first, apply the Depth Protection Serum to the stressed areas of unwashed hair – not on the roots. Leave the serum in the hair during coloration to protect your hair structure. Mix the color emulsion and the developer, then apply the color to the hair. After the exposure time, rinse thoroughly and gently massage the care balm into the hair.
