Well some of us (me, for example) can have a tendency to get thin, stringy curls. Which I don't find terribly attractive on myself. So, I am always desperately in search of clumping. And actually, when I have good clumping, it tends to look like I have better volume. The stringy curls lie flatter against my had, but the clumpier curls - because they're fatter - give added volume to my hair.
Although, I don't know if I helped at all.
