This is a deep purple colour and tones my highlights into a beautiful light ash colour, I only leave on for 3 mins but if you leave longer the colour will be more intense and you get the benefit of Olaplex technology in a lovely smelling shampoo. It really looks after your dry hair, mine actually moves now because of the condition. Lovely!
