Circling back to my original issues, I've come to find that over the past two years I've simply been washing my systems the wrong way.
It does annoy me that out of the two salons that served me to date, no one ever bothered to tell me the "normal" way of washing your hair — rubbing in the shampoo by massaging your scalp with your fingers in a circular fashion — causes too much friction between the open follicles of the dead hairs in a hair system, and that it's critical to employ a linear routine like in the video below. But at the same time I'm pretty happy that ever since I started to wash my hair this way I've experienced way less tangling and shedding, so there's that.
