Hmm. Maybe someone else can. Perhaps you can ask the Mods, about how to find it?... It was something along the lines of, can scratching your head often, make you bald….
I remember, because I responded. My father has something similar going on, on his head, and the VA prescribed him a shampoo, that was prescription only. I occasionally get itchy, tiny, scabs, in my beard, when the seasons change. I tried the stuff. And it helped. I’ll try to find out, what it was… I think I still have the bottle, but due to my multiple floods, my belongings (what’s left,) are scattered between several places I lived, when homeless for 6 months…
I’ll get back to you.
