L\'Oréal Professionnel Dia Light 10.02 is specifically formulated for maximum shine and condition on coloured hair. Ideal for adding shine to hair that has previously been coloured, weakened or sensitised. This 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. Dia Light is great for offering a colour refresh to top up the vibrancy of your colour in between your usual permanent colour services.
