Our first acidic tone-on-tone colour creates glossy luminous looking reflects and vinyl shine whilst respecting the condition with natural-looking colour that gradually fades away. Ideal for previously coloured or weakened hair or even for those that just want to add a subtle richness or gloss to their natural hair colour. DIA Light is great for offering a colour refresh to top up the vibrancy of your colour in between your usual permanent colour services. The fast development also makes it ideal for those with busy lives and who are short of time. With the technology of DIA Light, your hairdresser will be able to create a truly personalised colour, tailored to you. Brand New Tube Sealed in Box.
