Did you end up finding a solution for your frizz? My hair is a lot like yours. I go back and forth between Aubrey Organics and baking soda since I'm trying to stay natural/organic. The baking soda doesn't usually cause me a lot of frizz, but it dries my hair out after awhile. Everything else I use either frizzes me big time or takes my curls out
Since you have low porosity, what do you use to condition? I'm having a hard time finding something that won't weigh my hair down.
