Formulated without ammonia, L'Oréal Dialight tone-on-tone acid cream gel color system is a semi-permanent colorant that provides a color bath with the ideal shade for color-treated or sensitized hair.

It does not damage the hair, nourishes the hair, and has a renewing effect on the hair fiber. It only takes 20 minutes to apply and gradually disappears in a subtle way.

Application: This product is intended for professional use. Dialight coloring can cause an allergic reaction, which in some rare cases can be severe. For this reason, it is mandatory to perform a skin allergy test before use, which consists of applying a small amount of dye to an area of sensitive skin such as the inside of the elbow. If there is no reaction after 48 hours, you can proceed with the global application of the product over the entire head.
