I'm naturally porous, so I can relate!

Here's what I do -

Either I scrunch condish into dry or misted hair, then get in the shower and low-poo or clarify,

Or I get in the shower and put essentially a DT (a good RO with honey and EVOO, sometimes protein added), leave it on while I shave, etc. Then I'll detangle, low poo my scalp, then rinse it all.

I follow up with a LOT of LI. (I actually use 2 - one in the shower so I can do a final comb through, and then another when I get out and am scrunching in clumps and curls!)

I do everything upright. I might tilt my head forward or side to side, but I never do upside down.

HTH!

I think the actual original post on this says to spritz and condish before the shower, then get in the shower and rinse, then low poo the scalp. I can't recall if it suggests to follow with a RO or not. It also said to rinse upside down - I get way better clumps when I don't do that, but to each his/her own!
