Formulated without ammonia, the L'Oréal Dialight coloring system is a semi-permanent dye in the form of an acidic cream-gel that provides a color bath with the ideal shade for colored or sensitive hair. L'Oréal Professional Dialight is an ammonia-free acidic cream-gel color that gives hair rich and radiant reflections after application, resulting in a glossy finish, vinyl shine, and exceptional uniformity. It does not damage the hair, nourishes it, and has a regenerating effect on the hair fiber. The application takes only 20 minutes and gradually fades in a subtle way.

Application: 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 essential to perform a skin allergy test before application, where a small amount of color is applied to a sensitive area of skin, such as the inside of the elbow. If no reaction occurs after 48 hours, the product can be applied globally to the entire head.

Preparation: Wear gloves. Do not use metal 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 whole tube of 50 ml plus 75 ml DIACTIVATEUR) and choose the volume according to the intensity and desired coverage: 6 vol (1.8%) or 9 vol (2.7%) are used to give colored and/or sensitized hair reflections or shine. The application time is 15 to 20 minutes. 9 vol (2.7%) or 15 vol (4.5%) are used to add shine to natural hair.

Tip: Wear gloves. Apply generally to dry, unwashed hair with a brush. Observe the application time. Mix carefully. Rinse the hair thoroughly after the application time.
