I was on the fence when I had long hair. I cut my hair though, to a bob, and then found this in my cabinet, and now I use it every second day. As soon as the sample is up, I'll be purchasing.
It gives A LOT of volume, but isn't sticky or shiny. It also doesn't make my hair feel coarse -- in face, it's like it's thicker but softer. I also notice it cuts down a lot on shine, so I really appreciate it the second day after a wash, when I don't want to have to shampoo my hair, but need lift and texture.
It doesn't have a strong scent at all...in fact, though I use it so often, I really can't even describe it's scent, so it's not really a factor.
Also, I worried the pump would clog, but so far, it hasn't.
