This dye is really great. I used it for the first time about three months ago on hair bleached to a golden blonde, and I was instantly thrilled with the result. I suggest leaving it on for at least 45 minutes - when I do it lasts between 6 and 8 washes before it starts to fade. The color is BRILLIANT and truly 'shocking' when you first dye it. I would recommend this for anyone. -Sarah-
