This bar has lasted me so much longer than a normal bottle of shampoo would. It smells great, a little bit goes a long way, and it gets my hair really clean without making it dry (I only use the shampoo, no conditioner). I also wish there was a better way to store it. I keep it in a little dish in my shower, in a place where it can stay relatively dry. But after a while, so much of it gets stuck to the bottom of the dish, and will likely end up going to waste. Effectiveness It might just be because I have really thick hair, so it's hard to fully rinse out, but I do get some buildup on my scalp from this product. So I occasionally have to switch to another shampoo to solve this problem. Scent Smells great! Something I really like about it, is it's scent seems to be unisex. My husband uses it and he doesn't have to worry about smelling like a pretty flower, and on the same token, I don't have to worry about smelling like some kind of aftershave. Since we can share, it frees up space in our shower.
