So I dabble in hair dye. So much so that I'm practically a pro at it and after having red hair (burgundy, crimson red) for 2 years yet it's so healthy and soft people have me dye their hair and it always comes out looking great! I did half and half black and blue once, using Ion's AQUA. After a powerful color stripper, the blue still didn't come out. So, I just dyed on top of it. Anyway, my friend wants perrywinkle-ish blue hair and I tried manic panic, but it didn't set in at all. I'd like to Ion's Azure hair dye. Is it as hard to wash out as Aqua? I've heard Aqua will stay in your hair for forever is the same true for Azure?
