L’Oréal Professionnel gives your hair colour and shine with Dia LightHair colours & tints often damage the hair because they are too aggressive. The intense tone of L’Oréal Professionnel is different. The revolution of the tints balances the structure of the hair out again and in this way smooths the hair. Through this, the hair becomes so silky after colouring that it is like it has just had a care treatment. The innovative intense colouring is based on a unique acerbic technology. Because of this Dia Light is so unique amongst hair colours & tints because it is especially for sensitive and even permed hair. But naturally you can also use the 37 wonderful shades for normal hair. L’Oréal Professionnel and Dia Light supply your hair with intense colours, with vibrant reflexes and a unique vinyl shine. You can’t just see the silky smooth surface of your hair but you can also feel it.
