It leaves your skin feeling smooth. It has a nice, elegant scent that doesn't feel cheap. I don't feel like I have to have this, but I don't dislike it, so I might buy it again.
I was buying some for travel and was attracted by the fact that it had been on the best-of list in the past. I wasn't particularly impressed, but I'm not dissatisfied either, so I'll buy it again if I have the opportunity.
I used the yellow one but this one is good too!
I bought it as a trial ^ ^ The scent is nice and it's well-balanced! I'd like to buy it again!
The shampoo lathered well and had a nice scent. I prefer the hair treatment to be a little more moisturizing, but it didn't leave my hair feeling rough after washing.
