It would take my hair a few days to absorb that much oil--even if I sat under my hard hat dryer for the entire time! I use minute amounts of really rich products most of the time, in addition to frequent haircuts.
Most of the time, it takes my hair a while to absorb my styling products even after my hair drys. My hair just gets better as the day goes on.
I'd be careful of using oils and butters in copious amounts if your hair is truly low porosity.
