I bought the single-use pouch. Once it dries, it's as smooth as the name suggests. It's light and refreshing. I don't like perfume-like scents, but this one has a nice, not too strong scent. I'm debating whether to buy the full version...
I prefer smooth shampoos because they cleanse more thoroughly than moist types. They cleanse thoroughly but also leave hair moisturized, making them easy to use.
I also use the shampoo and out-of-bath treatment from the same line. My cat's hair is damaged, tangles easily, and tends to fall flat, so moisturizing products don't really suit me. This product has a light texture, but it's not too heavy, so I like it because it's just the right balance. It makes my hair less tangled and smooth, and I'm very happy with it.
I was originally using a different type, but this one is also smooth and I love it!
