Colorinsider is a MATRIX hair color found in this collection along with its 30-volume developer, for a complete salon service or for those experienced with hair coloring.
Before starting, choose the shade based on the natural color and the desired goal: coverage, a tone change, or slight lightening. Prepare the mixture in a bowl following the indicated proportions, apply it with a brush starting from the roots, and respect the required processing times. A skin allergy test must be performed 48 hours before each application. After rinsing, a gentle shampoo and conditioner for colored hair will help maintain the results. Discover all the tips in our guide to colored hair.
