L’Oréal Professionnel DIA Light is an acid gel cream tone-on-tone hair colour. It doesn't lighten or sensitise the hair, but fills it with moisture and conditions for maximum shine, making it a firm favourite with professional hairdressers. Its zero lighting makes it perfect for use on coloured or sensitised hair, delivering beautiful shine and condition.
