L'Oréal Professionnel Dia Light 50ml is an ultra-mild, ammonia-free semi-permanent hair dye specially developed for sensitive, fragile, damaged, or previously colored hair . This professional tone-on-tone formula offers an exceptionally soft color experience with a shiny, deeply personalized result without weighing down the hair structure.
Thanks to its caring gel-cream texture, the color spreads evenly throughout the hair and adheres subtly yet intensely to the hair shaft. Dia Light gives hair a beautiful, translucent color reflection with a shine that lasts up to six weeks . The color fades gradually and naturally, without harsh lines or root regrowth—ideal for clients who want a refined, low-maintenance look.
The unscented, ammonia-free formula ensures maximum comfort during the treatment, even for clients with sensitive scalps. Dia Light is also a perfect choice for personalizing, neutralizing, correcting, or deepening existing shades. Ideal after lightening, for glossing, root melts, color melts, tonal shifts, or even out porosity.
Dia Light is part of L'Oréal Professionnel's premium Dia range, loved by salons worldwide for its gentle formula, deep shine, and reliable performance.
