How Dia Light works in professional colour services

L’Oréal Dia Light 60ml is a tone-on-tone, acidic demi-permanent colour designed specifically for sensitised, coloured, or lightened hair.

Its low-alkaline, ammonia-free formula deposits colour without lifting the natural base, allowing you to neutralise brassiness, refine tone, and add a high-gloss finish while respecting the hair’s condition.

Because it works in the acidic zone, Dia Light helps close the cuticle and enhance shine, giving hair that smooth, “glass hair” feel clients love.

In the salon, it’s simple to use:

• Lighten or colour as required

• Apply Dia Light as a toner or gloss

• Process, rinse, and finish with beautifully balanced, shiny hair
  
  

It integrates seamlessly with L’Oréal Professionnel lighteners, Majirel, and other colour systems, making it easy to build into your existing workflow.
