So, from what I understand now,
Wen and Hair One products really are "co-washes", as in "conditioner wash", because they don't have ingredients that work as cleansers. They are "no-poos" as well, because they don't have shampoo ingredients, but DevaCurl No-Poo is not a co-wash.

In that case, I think I have had my terminology correct, and I have been "co-washing". At this point, it's "modified CG", but it's not low-pooing. I'm pretty sure the only time I've "low-pooed" is when I do "clarifying" washes every six weeks or so.
