I have new thoughts about hair loss. I think the muscle tension itself is not the only thing that is responsible for it. I think the more developed muscle and muscle tension explain why men and women are balding in different pattern and why men's hair loss is more extensive. But there is one questioning thing: What causes inflammation in the body and excessive tissue dht that triggers fibrosis and/or calcification? I think different people have different causes of their hair loss but only the result is the same. Imbalance of testosterone: estrogen ratio, elevated prolactin, cortisol, insulin resistance, liver issues, high blood pressure, thyroid issue all may cause hair loss, but you should be GENETICALLY PRONE for hair loss to occur. You won't lose hair unless you are genetically prone to it. Some people won't lose a single hair because of their hormonal imbalances. I saw a man in his 80s who hadn't loss a single hair despite having extra body hair. It depends on the balances of your calcification regulators, your body's ability to make fibrosis. I think people who don't lose hair despite being obese and unhealthy lack the genetic ability of increased DHT to trigger development of fibrosis or something and do not.
Women typically don't lose hair till their forties or beyond when estrogen levels decline. So there is connection between testosterone and estrogen ratios. Young men with androgenetic alopecia have similar hormonal profile as women with polycystic ovary syndrome.
So hormonal imbalances, genetics and muscles are the real cause of hair loss. It's no coincidence that the prevalence of male pattern hair loss gets higher with the age as men's testoterone levels drop and individual's health declines. To treat male pattern hair loss we should focus on primarily on fibrosis and health improvement. I posted an articles that explains why the areas where the hair loss occurs are hard, stiff and shiny. Beacause of collagen overproduction. Different people have different susceptibility to hair loss. Some Don't have the susceptibility to go past Norwood 2, some stop at Norwood 3,but others have the ability to develop so severe fibrosis leading to almost complete baldness. People who never go bald lack the genetic ability to create fibrosis or retain good health condition, hormone levels and healthy lifestyle through their life. The second type of people are rare it's usually the first.
Today's generation is balding ridiculously early. I saw old photos of my grandfather collegues( men in their forties) and no one of the has andvanced balding pattern Norwood 3 or worse. Today it's pretty common to see men balding in their twenties and early thirties. It's because of all the crap we eat, the exposure to radiation, poluted atmosphere, environmental stress and sedentary lifestyle.
