I can't understand a lot of what you wrote--all those letters make no sense to me. I can try to answer what I did decipher. It's typical for people with curly hair to think it's coarse--because it's dry. If you've had the hair analysis, I'd go with that. My hair is low porosity and it's no longer dense. When I worked, I would shower at 6, not use any product, towel dry, diffuse for a bit and head off to work. It wasn't unusual for it to be damp at 11:30. If that gives you an idea.
Many of us start with Deva, think we like it and then move on to other things. The best thing to do is to look for people with similar hair and see what they use (in signature.) That's the best place to start.
