I was given a bottle of this by a friend who didn't want it. Usually I use the slightly cheaper Schwarzkopf range, so I was interested to try this one.
It was easy to apply (rub in like shampoo) and I only needed to leave it for 15 minutes. By the time I washed it out my hair was a lovely dark grey-toned blue.
As I wash it and swim in chlorine with it it seems to be fading to a paler aqua green colour. I'm pleased the colour seems to be holding better than previous wash-out dyes I've used.
In future when I want a cheap and easy colour change I'll be getting my mits on this stuff again.
I used the dark blue colour of this dye and I have mixed opinions on it. First of all, it showed up on my light brown but unbleached hair quite clearly, which is a plus of you want to dye your hair but shy away from bleach. However, this dye stained my hair entirely. Once the blue had washed out, I was left with a muddy green colour that would not leave my hair until I caved and bleached it out. This may be because of blue dye itself, which always seems to stain.
