L'Oreal Dia Light (50ml)- Now Discontinued Please note that we are in the process of transferring to the new size packaging for DiaLight and is being phased in over the coming weeks. If the shade you are looking for is not available please check the new listing for the new packaging. Some shades may no longer be available going forward so please check. L'Oréal Professionnel Dialight is an acid gel cream tone-on-tone hair colour that doesn’t lighten or sensitise the hair, but fills it with moisture and condition for maximum shine. Dialight is a versatile ammonia free colour that allows you to mix shades, and can be used with L'Oréal permanent colours as part of a colour matching service. Dialight is ideal for coloured or sensitised hair as it offers zero lightening and delivers ultimate vinyl shine and condition.
