This is a great product to use on wet or dry hair. I generally use it to smooth fly-aways on dry hair. It smells great, lasts a very long time (mine lasted about a year with regular use), and works great when I'm on the go in the mornings whether I leave my hair up or down. Only complaint is the pump only reaches about 75% of the way down (as do a LOT of products out there), forcing you to waste about a month's worth of product!
