Breakage occurs with both protein overload AND moisture overload so it's hard to tell. You also mentioned a lot of shedding (IIRC). It was also described that you used a lot of moisturizing products.
Are you sure the products you were using were actually moisturizing?
Baby food banana, honey and EVOO is a very moisturizing DC mix. Personally, nothing makes my hair as soft as when I add 1 tsp of sea salt to any DC mix (but I wouldn't recommend experimenting with that just yet).
Hibiscus powder is also very moisturizing.
The good thing about protein is that it assists the hair with taking in moisture. Maybe you could DC overnight or for a few hours. I love to DC with heat but some get better results when they don't.
Sorry I couldn't help more
