This is a great body wash that can be used as a hair wash in case of emergency. I travel extensively, and I've been using this wash to wake me up despite 12+HR-difference jet lags. The smell is strong -- and if you notice that you like when a smell "invigorates" you (like me), then I highly, highly recommend this. The major note is eucalyptus, but the other smells work tremendously well with it. But my S.O. just says it smells "foresty fresh." The smell is the reason I purchased a full size of this product after trying a sample - it wakes me up regardless of how I feel or what I did the night before. It is now my daily body wash.
Cons: I wouldn't use it exclusively for my hair -- it kinda strips it and makes it feel dry (it leaves my skin feeling great!). BUT when I travel, I do use it for both hair and body, because its better than most hotel shower gels and I only have to carry one bottle with me. The only other con is that it's pricey -- but you can't find this smell profile anywhere else.
