Hey curlisue. KCCC is very very concentrated. I bought my first jar in the beginning of December I think and I still have it. It's down to the last tenth of the jar. That is enough for at least two to three more weeks for me. It's well worth the price. If we're going by how long it lasts you, I think KCCC is much cheaper than other gels and gellies and mousses. What have you. I think it's difficult to quantify how much I use normally bc of KCCC's consistency. It's very gelatinous and mucous-like. So I just know when I have enough on my fingers but I'd say I use anywhere from a dime to a quarter size for each application? It spreads very easily. Once you get the hang of it you'll know how much is in your hair and whether or not it's enough. Oh also be aware for most people KCCC increases their drying time by a few hours. But if you diffuse that's no problem.
