In the month I've had my conditioner, I've probably washed my hair 20 times or so, no cold showers, no special shampoo, and my hair still looks awesome. It has definitely faded a shade or two, but I have a feeling if I had used the deep conditioner after every five washes or so, that would take care of the issue. The conditioner leaves my hair soft, and has a somewhat strong scent of ... spearmint, maybe? But it's not off putting. This color doesn't stain my hands, and when I rinse it out of my hair, the water definitely runs more clear than blue. This bottle will easily last me another two weeks.
The only reason for a four star instead of a five star review is that it leaves my curly hair a little flat. It doesn't feel heavy or weighed down, just leaves my hair smoothed out, which some people are probably in to, but I like my curls. If they came out with a line for different hair types, I'd be the first to try it.
Overall a solid product, and one I'm excited to try in different colours!
