Allowing Express Tones shades to process longer than the recommended 5 minutes allows stylist to manipulate the final result. With a deeper EXPRESS TONES Rose Gold look on the hair, the final colour after VIVIDS will be deeper. You don't have to compromise the integrity of the colour with other tones to make it darker, and this also lends for easier multi-dimensional colouring.
