Ammonia-free intensive tint with acid technology for particularly gentle length and tip balancing as well as individual colour enhancement with incredible shine. Loreal DIA Light is ideal for coloured or sensitised hair. Perfect for luminous and shiny highlights. In this water-based environment with an acidic pH value, the hair fibre swells only slightly and is therefore protected to the maximum. The colour pigments develop in perfect harmony with the colour pigments already present in the hair fibre. Thanks to the structure-balancing smoothing of the hair surface, the hair feels as smooth after colouring as after a care treatment and shines with an intensive colour result. Properties: Ammonia-free intensive tint; Up to 70% white hair coverage; Based on acid technology; Also ideal for refreshing colour; Maximum protection of the hair fibre; Lasts for 6 weeks; Application: Always adhere to the mixing ratio of 1:1.5. Only use Loreal DIA Light with Loreal Diactivateur 1.8%, 2.7% or 4.5%.
