Professional Acid Gloss Hair Colour for Tone, Refresh & Shine

L’Oréal Professionnel Dia Light 60ml is a professional demi-permanent hair colour designed to tone, refresh, and enhance shine on coloured, sensitised, or lightened hair. Developed for salon professionals, Dia Light delivers precise tonal results with a no-lift, acidic pH formula that respects hair integrity while enhancing softness and luminosity.

The latest evolution of Dia Light features a 1% Hyaluronic Acid complex, helping support hydration, smoothness, and hair resilience after chemical services. This advanced acid-gel cream technology allows colour to adhere evenly while maintaining a lightweight, conditioned finish.
