L'Oréal Professionnel Dia Light Semi-Permanent Hair Colour 50ml

L'Oréal Professionnel Dia Light Semi-Permanent Hair Colour (50ml) is an ammonia-free, tone-on-tone formula specially developed for previously coloured, weakened or sensitised hair. Using innovative acid-gel cream technology, it enhances, tones and neutralises without lifting, making it the ideal choice for refreshing colour between permanent services and perfecting lengths and ends with a high-shine finish.

The unique formula seals the cuticle for a vinyl-like gloss, leaving hair up to 30% more conditioned after use on bleached hair*. With a wide palette of intermixable shades from warm beige to cool ash, Dia Light offers complete creative freedom across all hair bases, delivering customisable colour results with enhanced softness and luminosity.
