This hair dye is really good, although it does bled a lot, and starts off a really black/blue colour, but after about 2 weeks it was a lovely blue colour and then started going green after about 4 weeks, i've had the dye in for about 2months without topping it up and its still a beautiful bluey/green colour, i'd definately recomend this to others wanting a nice blue/greeny colour, it's stunning
