L’Oréal Professionnel Dia Light 5 – Light Brown is a color treatment specially formulated to gloss, tone, and refresh the hair without weighing it down. This semi‑permanent color is enriched with hyaluronic acid, providing instant hydration during the coloring process while actively combating visible signs of damage such as dryness. Thanks to its unique formula, Dia Light neutralizes unwanted undertones after lightening or balayage and is ideal for reviving faded lengths and ends. The result is visibly healthier, stronger hair with an intensely glossy color that lasts up to 6 weeks.
