I know this question wasnt for me, but I use about a nickel size blob of satin roots and maybe two nickel size blobs of the jam (usually a llittle over a nickel size though). I find I don't need much of either product, which is awesome. I've used and used my bottle/jar of products and have hardly made a dent. My hair is tailbone length (tapered, so kind of thin at the bottom) and medium thickness. HTH.
ETA: I find my drying time to be much shorter than when I used KCCC.
