Gravity causes hair loss


#1

Some genius doctor came up with the idea that gravity is the reason we are losing our hair.

Quote:

"Dr. Ustuner believes, is the weight of the scalp on the hair follicles. In youth, the scalp has sufficient fat tissue under the skin, and it is “capable of keeping itself well-hydrated,” buffering the pressure on hair follicles. But with aging, the skin and underlying (subcutaneous) fat become thinner, and the pressure on the hair follicles increases. Testosterone contributes to thinning of the subcutaneous fat. In women, estrogen prevents thinning of these cushioning tissues, at least until menopause.

Aging and Testosterone-Related Changes Create ‘Vicious Circle’ Leading to Hair Loss As the cushion decreases, the hair follicle must strive against higher pressure, requiring more testosterone to achieve normal growth. This “local demand” leads to a buildup of DHT levels in the scalp, but not in the bloodstream. Rising DHT levels cause further erosion of the subcutaneous fat – creating a “vicious circle,” according to Dr. Ustuner.

The hair growth cycle accelerates in response to DHT, but it’s not enough to overcome the increased pressure. Over time, the hair follicle becomes smaller and smaller, resulting in progressively increasing hair loss."

This has been discussed and debated before with the doctor (Dr. Emin Tuncay Ustuner) who came up with this theory, see link below:

Initially, as I recall, the doctor’s explanation was that DHT wasn’t involved in male pattern baldness at all. Now, it looks like he can’t escape the involvement of DHT… the theory now says that it “helps explain DHT’s role in Androgenetic Alopecia”.

So, which is it? I could say that DHT is responsible for male pattern baldness, but it’s the sun’s rays shining on the scalp that actually causes the hair loss.

The point is that DHT is the ultimate cause.

The theory sounds ridiculous but if you read his papers, he seems like an intelligent man, i like how he made an attempt to explain why scalp hair and body hair react differently to DHT.

There is nothing revolutionary about explaining why DHT (or other hormones) have different effects on different parts of the body. This has been studied for decades regarding DHT, and an incredible amount of detail is already known about this. DHT does have different effects on scalp hair follicles compared with beard hair and body hair. Did you know that there are also DHT receptors in the heart and the brain, and the hormone has surprisingly different effects on these organs? And that not only that there are different kinds of DHT receptors in these organs, several different types of known DHT receptors, with different properties and effects.

So - if this doctor is using the fact that DHT has different and opposite effects on hair follicles in the scalp as compared with, the beard or scalp, to claim that DHT couldn’t be the cause of hair loss, he just doesn’t understand the role of different endocrine receptors responding differently in different parts of the body. This is something that has been well known to endocrinologists for decades.


#6

So you are saying DHT receptor is the reason why scalp hair and body hair react differently to DHT? Scalp follicles have an abundance of DHT receptors and body hair follicles little or none?


#8

It’s extremely complicated with lots of different variables. The “DHT” receptor is created by the “AR” gene, and there are a bunch of different types of mutations of that gene, which result in receptors having different levels of sensitivity to DHT. Any of these mutation types can have different distribution on the body, depending on that individual’s own genetics.
