Those little bottles of clear Neutrogena shampoo are lovely. They get my hair squeakily clean and smell like baby powder. I know you get them it in regular hotels and they aren't a premium product but I really like the fragrance. Also the corresponding conditioners- pinky-peach colour.
I have to say that though I liked the Bulgari The Vert shampoo, gel and body lotion that I tried at a recent hotel stay- I'm not going to rush out to buy them. Not sure if it was the (sad) expectation that I had of Bulgari being mega luxurious and addictive just made me hope for too much. I liked it but wouldn't buy it for myself.
Slight OT- the Delta intl biz amenity kit has occitane products that really introduced me to these gorgeous hand creams, lip balms etc.
