This was just okay, it didn't dye it exactly as blue as the one show, it showed up more as a green on my bleached light brown hair.  

color is very pretty (kind of teal-turquoise), I had my hair bleached and colored light brown before I use this, so I guess that is the reason why the green color last longer than 2 weeks. I'm in my first month now and the color still hasn't faded completely 

Disappointed :(

Didn't work with natural dark hair / brown hair.

My hair color still same like before but bit dryer.

It's make my hair soft little bit but looks dry.

Im still curious to try with red colors. Hope better luck this time
