L'Oréal Professionnel Dia Color — tint and shine without lightening

Dia Color gives hair a new tint and more shine without lightening your natural colour. A change that starts gently.

Dia Color — warm copper in long waves

L'Oréal Professionnel's Dia Color is a tone-on-tone colour treatment: it adds tint and shine to the hair without lightening its natural colour. That makes it suited to anyone who wants to try a new direction that doesn't have to feel final straight away, and to hair that mostly lacks shine. The photos show how wide the palette is, from warm copper and deep burgundy to curly copper-brown and a soft mocha. The end result depends on the starting colour and on the hair itself. That's why we choose the shade together with the client and, if needed, test on a strand first. Because the colour is mixed in the salon, we set the shade and the intensity per client. In winter, when cold and dry air make hair look dull faster, a gloss colour is one of the lightest ways to bring colour back into the hair.
