Update:
The Pure O.N.E. African Black Soap Prepoo Mud Mask is a winner!
I applied it at the sink, detangled with it, and left it in for a little longer than 15 minutes. it soothed my scalp. I rinsed it out in the shower and hair felt luxurious (a handful of the 17 website reviews said it was drying, but I didn't have that experience). I saturated my naked hair with the organic rice water, did my other shower-related tasks, rinsed out the organic rice water, and at the sink started the moisturize, seal, and style process.
I was purposely trying to shave off time with this combination of products and these techniques. I entered the shower just once with this process!!! I am sure that my hair would benefit more were I to keep the organic rice water in longer. However, for the trade-off in time and number of times entering/exiting/re-entering the shower, I'll take it!
The only thing I would change is to reintroduce the Cantu ACV Rinse (or some kind of tingly, liquid scalp treatment): The prepoo is super thick and it took a little work to apply to the scalp.
Now I need to determine
How often do I need to do a moisturizing DC and a proper protein treatment if I'm using the prepoo mask and the organic rice water each wash day? This is going to take trial and error and note-taking.
