Just my thoughts - I think the inflammation of blood vessels leads to shrinking capillaries, less blood flow, which in turn leads to calcium accumulation (calcification), followed by fibrosis. Of course this whole process takes years to occur. And about your question about calcification occurring elsewhere in our bodies... I had an MRI a month ago and found to have small calcium deposits called pleboliths in my pelvis, so it can absolutely occur. They aren’t serious and are common. Bottom line is I think the inflammation of our circulatory system in the scalp (mostly driven by DHT but absolutely not the only culprit) is responsible for male pattern baldness. The only evidence I can give to back up this claim is the fact that every successful treatment for male pattern baldness addresses inflammation in its own unique way... minoxidil, finasteride, seti, microneedling, pge2, cetirizine all either reduce inflammation via inhibiting the DHT/PGD2 pathways OR improve circulation via vasodilation.
