Why does the Luminance kit have 3 steps?

Luminance has a 3 plus system, a protective shield that protects you before, during and after colouring. This system consists of the pre-treatment enriched with Keratin. What is Keratin? It is a fibrous protein that is part of the components of the hair, it is responsible for protecting the interior of the hair, giving it shine, hydration and strength. After this step we continue with the coloration, we have a portfolio of 29 shades between blonde and gold, ash, red, copper and mahogany and brown and dark with a formula that has rice protein, wax and honey, a component natural that helps restore the hair fiber. The last step is to apply the post color treatment that has Collagen and Omega Plus that help lubricate the hair follicles and thus add elasticity and shine to your hair.
