So I'm having trouble with my very porous hair losing moisture between washings. I'll have a great hair day the day prior, wake up to pretty good 2nd day hair, but by hour 36 or so it feels drier. It will frizz more when touched, tangle more, and start to lose some definition.

I already use a lot of moisture in my RO, a good LI, and I already seal with oil. (usually Jojoba, sometimes SM's elixir.)

Any suggestions? I had less trouble in the winter when I was using a humidifier.

I'm wondering if I need to try scrunching in some additional LI or oil throughout the day? Maybe before bed? And again in the morning? I don't want to break up clumps or cause stringlets, etc, tho!
