Ooops! Haven't checked this thread in a while!
I'm not sure how to quantify... My hair is in a bob, so it's fairly short. To saturate my hair completely, I use a generous palm-full.
Maybe I can snap a quick pic tomorrow.
ETA: It's been about a month, and I've been having consistent results. So much so, that I recently purchased 2 more bottles of each conditioner.
