What is the purpose of the after-colour conditioner included in the box, and how should I use it?

The after-colour conditioner is a crucial part of the process, not just an add-on. After the oxidative colouring treatment, the hair cuticle can be slightly raised. This conditioner is formulated to smooth the hair cuticle, which serves several important functions. First, it helps lock in the colour by closing the cuticle layers, potentially improving colour longevity. Second, smooth cuticles reflect light better, which enhances the glossy look and the metallic, smoky finish of the Metallic Graphite shade. Finally, it makes strands feel softer and more manageable, counteracting any potential dryness from the colouring process. Use it immediately after rinsing out the colour cream, applying it evenly through the lengths and ends. Leave it on for the time indicated in the instructions before rinsing thoroughly with cool water for maximum shine.
