I'm going to see a dermatologist next month. But in the meantime..
I had scalp psoriasis. Chronic stress. That is all gone now. I haven't had flakiness or dandruff for weeks. Yet I still experience, in my opinion, chronic shedding - a few dozen strands a day for sure that I'm aware of. I've been using Clobex shampoo regularly lately, Nizoral on and off once or twice a week. I will otherwise use Hugo's Natural Balancing shampoo in the morning; I have to shampoo because after exercising my hair kind of looks like sh*t if I don't. Both the doctor and my hair stylist have said that my scalp looks healthy and not inflamed (red), or flaky. But the shedding continues to happen. The shedding wasn't a thing at first when I was diagnosed but now it is and won't seem to stop.
I really hope it does stop. I don't know if it is a side effect of the chronic stress I experienced a couple months ago, or something worse.
I am a very healthy individual otherwise: tip-top diet, supplemented properly, mentally and physically sound, well hydrated, I even try natural DHT blockers to cover my *** which may or may not be doing anything - 10ml pumpkin seed oil, 10ml flax oil, omega3 fish oil, 5000mcg Biotin, 15 minutes of inversion, dermarolling once a week, 10mg quality collagen peptides nightly, and far infrared sauna 3-4 times a week triggering HSP and blood flow and circulation throughout my body including my scalp which I think is far superior to scalp massaging.
Beyond this, I have nothing left to try until the dermatologist hits me with the best news I may ever receive, or the worst news of my life.
