I recently learned that there are actually three different types of the 5-alpha reductase enzyme, which produces dihydrotestosterone, and that this is the key to understanding what is really happening. I think that this should provide a fairly complete picture of events now. It is a form of the enzyme which is called SRD5A1 which is expressed in skin, hair follicles, and especially the scalp.
Anyway, try doing a search online for diabetes and alopecia. The two often occur together for a reason. It's the insulin which is the connection. https://academic.oup.com/endo/article/151/10/5030/2456459?login=false The insulin triggers the prostaglandin D2 expression and GPR44 receptor triggering in male pattern baldness. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6296667/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3319975/ Because insulin is both a protein structure and a hormone the enzyme trypsin is required for both its production and breakdown. That's the reason that issues with insulin can result in the release of trypsin in sebum and issues with the integrity of skin structure. https://pubmed.ncbi.nlm.nih.gov/11423485/
People with coeliac disease, such as myself, tend to be at higher risk of developing diabetes. I assume that I must possess genetic factors which have successfully prevented this outcome in me but I must have experienced the issues with insulin and/or insulin resistance. While insulin tends to induce vasodilation in normal blood vessels, by increasing nitric oxide levels, it induces vasoconstriction in microcirculation (small blood vessels in tissues). https://journals.lww.com/jhypertens...ICTOR_EFFECTS_OF_INSULIN_IN_THE_HUMAN.82.aspx That's the reason that decreased blood flow is involved in hair loss. http://glenncorp.com/wp-content/uploads/2014/11/ProCircul8-TDS.pdf
I can't be absolutely certain about this but I am assuming that the galea aponeurotica, which forms the pattern of male pattern baldness, is filled with microcirculation vessels. While male pattern baldness can occur in women it is less common. Still, I can't help but wonder whether this article might help explain. https://www.tandfonline.com/doi/abs/10.3109/01612840.2011.625514?journalCode=imhn20
