I just received this along with the conditioner as a gift. I love the scent, it is strong and lasts a long time. It also made my hair look great - very smooth and shiny. Usually my hair tends to look dry, but since I have been using this it stays silky all day.
This is basically hair perfume. The smell of Kai is incredible from start to finish, and you can still smell it the next day. However, it is not a great shampoo. I have fine, straight hair that frizzes in humidity. My blow dryer caused so much fluff that I had to use my flat iron immediately. Then after being outside for a few hours my hair actually became wavy. I don't know what is in this stuff, but it doesn't seem to be for people who prefer a sleek look. I will try it again with my Aveda conditioner and see if I can still smell the Kai without looking like a puffball. Not worth $34 in my opinion.
