Thanks at least I don't feel like the only one with this situation. It's weird, how I never paid attention to my hair, but I had curls as a little one, and it got straight (and it got brushed) but man in my teens, it was thick, poofy and big. Now again, its in curls, ringlets/waves, but just not the same volume, and yes, this smaller ponytail to what I remember, I used to break elastics and clips and not anymore, not even close. But yet, I have no patterns or anything (thank God) Maybe it will change again, or like you said, and the article, maybe it's just normal for me, and my hair pattern changed. I'm about like you with very few coarse ones, mostly medium texture/thick hairs and some finer ones.
Medium texture
Normal porosity
Normal elasticity
can get weighed down with lots of oils
