First off, this conditioner smells AMAZING!! (smell it at the store to see if you also love it!) I washed my hair yesterday and conditioned with this. It didn't leave my hair slippery and sleek right in the shower as most hair conditioners do, so I was worried it wasn't actually working and that my hair was going to be a nightmare to brush out. But, I got out of the shower, and my hair brushed out just as easy. (my hair also got that sleek feeling when I rinsed it out. just not while it was sitting.) I styled as usual, and carried on with my day. this was about noon yesterday. Since then, I've been outside, I had a 2 hour workout at the gym, lots of sweat!, while wearing a ball cap, and I slept a full nights sleep. It is now noon the next day and my hair seriously has that beautiful scent and smells like I just washed it! INSANE. I will never buy anything else! I bought the matching shampoo today but haven't tried it yet. I will review when I do.
