I think Kathymack would probably have a sample she could send you, try contacting her.
I got my first tub sometime in February, I think. I use it every day, my hair is a chin-level bob, and I have about 3/4 of a jar left. But I don't use it alone as a gel, either. I do little dollops of it mixed with ArcAngell all over my head.
Also, another thing to account for with me is that you can't go by just looking at my jar itself - one of the first things I did was scooped up a generous amount of it into a little plastic travel sized jar for the weekends when I'm out at my boyfriend's place.
