Umm... It's hard to say. I just scoop some out with my finger tips, once or twice, depending on how well distributed it was.

Maybe... The size of a walnut (in the shell)?? Idk! Hard to measure that, I guess! No more than that much, I'd say. And my hair is pretty thick and long.

I do use it over LI and sealer, and then put some gel over that.

I'm REALLY wanting to try it WITH the smoothie! Hopefully I can get out to pick some up soon!

Eta: my hair is pretty long - almost elbow length, is layered, and pretty dense (even though fine in texture.)
