My first question to you is, what are your properties?? Here's a link to help Curly Hair Basics | Live Curly Live Free I,personally, can't use mineral oil. Don't know if that's a low porosity thing, or not.

Not sure why a 16 oz product would only last you 3 uses?? Do you have a ton of waist length hair?? You should apply product to damp hair, at the very least. That way it will distribute better.
