I really really liked this stuff. I have dry, baby fine blonde hair that never really gets oily, but gets straw-like with frequent shampoos. It took some getting used to with this stuff - it felt strange to not have any lather, and it didn't feel like it rinsed out of my hair entirely - but the end result was worth it! Super soft, sleek hair that wasn't weighed down at all. (I did use a separate conditioner as well.)
I'm taking off a star for the fact that I felt like I had to use handfuls of product to achieve cleansing, though. I'd go through a bottle super fast.
