The smell is the first thing that hits you; I don't even know how to describe it, but it's wonderful. It lasted at least half the day. Nothing too heavy. Just a delightful wisp of scent when your hair falls across your face.
I was a little apprehensive when applying it because it seemed to make my hair and my hand sticky. I did have to wash my hand after applying, and it made me have (soon to be fleeting) second thoughts: was this just going to make my hair sticky and flat?
Any anxiety, however, left as I began blow-drying it, which seemed to take less time than usual. My hair went from feeling a bit sticky to thicker, sturdier, and fuller. It lasted all day, even into the morning.
I have short hair, about halfway in between shoulder and chin length, and I used about 6-8 sprays. At that rate, this bottle should last a while and will be a great value at the price.
I joke all the time about how I don't expect any product to give me "supermodel" hair; this comes pretty darn close, though!
