The ammonia-free tone-on-tone acid cream gel color system L'Oréal Dialight is a semi-permanent dye that provides a color bath with the ideal shade for colored or sensitized hair.

L'Oréal Professional Dialight is an acid cream gel color without ammonia that gives the hair rich and vibrant reflections after application, resulting in a shiny finish, vinyl gloss, and exceptional uniformity. It does not damage the hair, nourishes it, and has a renewing effect on the hair fiber. The application takes only 20 minutes and fades gradually in a subtle way.

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

Preparation: Wear gloves. Do not use metallic instruments. Mix the products in a bowl, shaker, or bottle. Prepare the homogeneous mixture of product and activator in a ratio of 1:1.5 (1 full tube of 50 ml plus 75 ml DIACTIVATEUR) and choose the volumes according to the intensity and desired coverage:

6 Vol. (1.8%) or 9 Vol. (2.7%) is used to reflect or enhance colored and/or sensitized hair. Application time is 15 to 20 minutes.

9 Vol. (2.7%) or 15 Vol. (4.5%) is used to add shine to natural hair.
