I just bought the Lavender one and the Lemongrass and Ginger one. I have to wait another 2 days though, I'm not due to shampoo until Thurday! Ahhhh, the suspense is killing me!!! I haven't tried using the bar without a rinse because I live in New Hampshire, and we have the hardest water ever. I don't think I would even attempt to use any bar without it. I will report back when I use the next one.
