L'Oréal Professionnel Dia Light 9.13 Demi Permanent Hair Colour is a professional demi-permanent gloss designed to enhance level 9 very light blonde hair with a balanced ash-golden reflect. Developed exclusively for salon professionals and freelance colourists, this ammonia-free formula creates refined beige-blonde tones while helping to maintain hair fibre integrity.

Enriched with advanced acidic gloss technology and a 1% Hyaluronic Acid Complex, Dia Light 9.13 supports moisture retention throughout the colouring process. The smoothing formula improves cuticle alignment, increasing light reflection and leaving hair visibly shinier, softer and more luminous. Ideal for creating natural beige blondes, soft champagne finishes or subtly warming cool bases without overpowering brightness, it delivers multidimensional tonal refinement with exceptional gloss clarity.

• Instant Hydration Boost: Replenishes lost moisture and combats dryness from the first application
• Stronger, More Resilient Hair: Helps reduce breakage by up to 3x after bleaching services
• Cortex Respect Technology: Maintains hair fibre integrity while delivering vibrant gloss colour
• High-Gloss Finish: Provides up to 82% more shine for luminous, reflective results
• Service Versatility: Ideal for glossing, toning and refreshing colour services
• Ammonia-Free Formula: Enhances client comfort while delivering professional performance

Expand your salon service menu with versatile colour applications:
