It felt like my hair was smooth for the first time in a long time. When I applied it, it felt a bit heavy and sticky, so I thought it would take a while to rinse off, but I was surprised that it rinsed off faster than any other rinse-off treatment I've used. I've only used the sample once, but I'll definitely buy it when I run out of the one I'm using now. It's based on a skincare concept, so I think it's different from other treatments in that it advertises that you can use it from the roots without hesitation. It's fragrance-free. By the way, the hair cream (used before blow-drying) didn't really suit me.
