That would be a start. And I would be very interested in the findings. There seems to be correlation even tho that doesn't mean there is causation. Like you said.. it comes in packages so to speak. If you are balding you most likely have other "undesirable" genetic traits. But yeah who knows what we would find tbh.

Agreed. Such as increased likelihood of benign prostate hyperplasia, high blood pressure, etc.

Yes. I have relatively high blood pressure already. But other than that I have it relatively good when it comes to genetic traits for a man who is/would be balding.

I had vitamin D deficiency even though I got plenty of sunlight and it was never a problem before...then I read to find out it is another correlated factor:

Study of serum vitamin D levels in men with premature androgenetic alopecia

Abstract
Background

Vitamin D deficiency had been associated with various hair loss disorders, such as telogen effluvium, alopecia areata, and female pattern hair loss. However, previous studies have not found a correlation between serum vitamin D levels and the severity of androgenetic alopecia.

Methods
A case‐control study was conducted for a period of one year in a public tertiary care hospital. Fifty males clinically diagnosed with androgenetic alopecia and 50 age‐matched healthy controls were recruited. Serum vitamin D levels in both cases and controls were measured by radioimmunoassay technique, and the results were compared.

Results
A total of 50 cases and 50 controls were recruited and analyzed. The mean age of the cases was 23 years and that of controls was 24.2 years. The mean levels of serum vitamin D significantly decreased in cases, compared to controls (20.10 vs. 29.34 ng/mL; P ≤ 0.001). Eighty‐six percent of the cases had deficiency of vitamin D (<30 nmol/L), while 14% had insufficient vitamin D levels (31–50 nmol/L). There was a positive correlation between vitamin D deficiency and severity of androgenetic alopecia (Androgenetic Alopecia), which was statistically significant (P ≤ 0.5). However, there was no correlation between the duration of sun exposure and serum vitamin D levels (2.36 ± 1.2 in cases and 3.23 ± 1.6 in controls, P value = 0.98).

Conclusion
Our study showed a significant correlation between vitamin D deficiency and the severity of androgenetic alopecia. This suggests that vitamin D may play a role in the premature onset of androgenetic alopecia. However, further studies on a larger population and the effect of vitamin D supplementation on the progression of androgenetic alopecia are required to validate the above findings.

you cannot crop the top of somebody's head and predict if they will bald or not even with proper measurements. Facial structure and galea both play a part.

I believe if you cropped up to where the hairline would be, you could get a statistically significant result. Not sure what the numbers would be though, obviously you wouldn't be able to predict every case.

I disagree. If you were to send me pictures of this man with his head cropped i would say he is norwood 1.

But look at his galea when you take away the box. He is not balding by any means but he is not norwood1 and i blame his galea

It is extremely importnant to see the galea too.

I mean sure, I wouldn't be able to tell you if he was a Norwood 1 or 2.

But 100% I could be sure he isn't a Norwood 7.

Yes. I have relatively high blood pressure already. But other than that I have it relatively good when it comes to genetic traits for a man who is/would be balding.

I cannot think of a genetic deficiency that I have other than receding/balding. Im 6’3 200lbs. Pretty good at every sport (not ridiculously good). Ridiculously analytically gifted (my major is very niche, 3.93 GPA @ a prestigious school). 115/70 mmHg.

I guess the addictive personality is a downfall. I smoke weed pretty much everyday and have a drive to work for a minimum of 8hrs a day.

In all, I do not think balding men have genetically worse traits than non balding men. In fact, I think it’s probably the opposite (wild speculation, that I hold no weight towards). But anecdotally, I have many friends whose fathers are fullheads yet they have leg issues/HBP/overweight etc.

Other genetic expressions may be more likely for worse conditions, such as dementia, Alzheimers, Parkinsons, etc. Some might include the types for which people with full heads of hair fall under.

So I agree that balding doesn't necessarily always guarantee "worse" traits, if you consider the picture holistically.

Of course I think everyone here would prefer to be balding than to be at much higher risk for those other diseases. I'm just speculating here though, this may or may not be the case. I don't think anyone who researches Alzheimers or Parkinsons would have a reason to suspect androgenic alopecia correlation with those conditions.

i guess but most people consider norwood 2 + balding

Well to an extent, but I think most guys here wouldn't be here if they knew their hair loss would stop at Norwood 3 or so. I think most people fear becoming a cueball with a horsehoe and having the bozo the clown look.

Take a look at some examples here, and cover their hairlines. Do you notice any correlative features?

I consider 2,5+ in young dudes as balding. A 45 year old man with a Norwood 2 will not be seen as balding even tho he technically is.. very slowly.
norwood 2 isnt slowly balding. A man can reach norwood 2 in his mid twenties and it could possibly stay that way forever.
Nikolaj coster waldau is norwood 2 and will probably never be bald. He is in his fifties.

they all have expanded, ridged galeas. If they had smooth galeas they would either have a full head of hair or be diffuse thinning with an intact hairline

Yes their facial features are weak and I also think Ritchie has a point when it comes to the galea. But the facial features stand out. Not a lot of forward growth. I bet a lot of balding people had problems as a kid with allergies and breathing/ resulting in mouth breathing.

True I'm just saying it is technically balding. Because at some point he receded from a 1 to 2. But yeah I would never consider someone like him, at that age as a balding man.

Yes that is part of it, but you missed the facial features like @Niki99 pointed out. Compare their features with the picture of the guy you posted.

men with poor facial features can keep their hair if they have a good galea.

@Niki99 David schwimmer is also a mouth breather and look at his face too. He has a smooth galea though.

I bet this guy is/was also a mouth breather
but is not balding.

@whatintheworld nikolaj coster waldau's galea isnt that bad. Sam worthington has an oddly shaped galea but it is not expanded and ridged looking like that of a balding man, he also has a horizontal face.

@Niki99 . Most men go through some form of hair loss so basically everyone is balding. A lot of people go from a rounded hairline to a straight hairline. That is technically hairloss too. Nikolaj for example is not slowly balding as you suggested. It will most likely stay this way for the rest of his life. David schwimmer also had a much more rounded hairline as a young teenager.
