I just got some after reading about it in Lucky. Normally I'm not so swayed by magazines, but it just sounded so amazing I had to see if it lived up to the hype. I tried it for the first time this morning. It's very thick - kind of like the consistency of honey, but thicker. You have to emulsify it in your hands a little to make it easier to spread into your hair. It did leave my hair really soft and shiny, and less frizzy than it usually is in the summer humidity. And it smells really good.
The jar was a LOT bigger than I was expecting after seeing it online. I think it will last a long time, because you only have to use a relatively small amount each time, so the $140 will probably even out to a reasonable per-use cost.
