Disproving muscle-tension hair loss hypotheses

[randomuser1]

Imo the calcification fibrosis or whatever is the driving factor in scalp tension is due to the simple mechanism of extremely tight supporting inner and outer neck muscles. This along with gravity (excelled by poor posture) pulls down on the galea, which inflames the inner tissues, with this resulting inflammation causing the above.

Do you have sources for supporting this? Why would tension on its own lead to inflammation and calcification? Yes, inside a muscle tension can lead to inflammation, but the issue are the hairs. Also, calcification is not explained by this.

On the other hand, there are literally dozens of studies showing that Androgenetic Alopecia is correlated with metabolic syndrome and insulin resistance:

Metabolic syndrome and insulin resistance, in turn, are known to cause both inflammation and calcification. The latter especially because of atherosclerosis. Summoning calcium is the body's standard response to vascular damage. And the scalp is highly vascularized. In fact, hair follicles can create their own capillaries to connect to the head's blood supply.

I am not saying that scalp tension plays no role. I think it does. The most important mechanism is that tension leads to fibrosis when inflammation is present. But what causes the inflammation (which scalp tension concerts into fibrosis) and calcification? Metabolic issues.
