There are 4 shades in the L'Oréal DIALIGHT Red/Copper/Burgundy family ranging from a 4.20 (Intense Iridescent Brown) to a 7.43 (Copper Golden Blonde). It has an innovative acid-gel formula that's free from ammonia and won't lighten or sensitise hair.

Instead DIALIGHT delivers luminous reflects and gorgeous shine with great condition, making it perfect for coloured hair. Its shades are perfect for refreshing an existing colour between two permanent hair colour services.

To get the best results from DIALIGHT, you need to mix it with its specially created developer DIACTIVATEUR. Mixing ratio is 1 part colour to 1.5 parts developer and development time is just 20 minutes.

Each shade comes in a 50-ml tube.
