Have wavy, oily, very long hair. Tried a lot of things to add volume without weakening hair or making it greasy - this is one product that works. It doesn't make your hair feel as though it's got product in it, and for 36 hours after use my hair supports itself standing up on my head. Fluffy is the wrong word but it doesn't sit flat like it usually does, which helps cut down on its greasy appearance.
It's a weird consistency, similar to the white of an egg before you beat it, but it lathers well. The smell is a tad strong for me (but I often have smell issues). Does feel like it never washes out fully while in the shower, but like I said, hair doesn't feel as though something has been added to it once dry. Overall, I'd say the description is 100% accurate - it does what it says and nothing else.
