Environmental factors involved in AGA ?!?! (Propecia, Spiro, DHT & hormones ...)

I have a hard time buying the "I wasn't losing hair until I came to the US" arguments because everyone can point to a time earlier in their life when they weren't losing hair. There are also a number of guys who insist that masturbation causes their hair loss because they started doing both during their teens.


Do people in the US have more hair loss than Asia? Probably.

We also have more caucasians than Asia. A lot more. That's where the MPB genetics are most prevalent.

And when it comes to intermarrying, that's VERY relevant. Even when American-living Asians stick to marrying partners that appear to be fellow Asians, there is a MUCH higher probability of Caucasian intermingling of the genetics somewhere back on the line. A person can have a whole extended family of a single race and still be carrying genes from some other background that was mixed in 3 generations back or something.

(And although the rates are lower, Asians themselves still have MPB too. It's not like they categorically need Caucasian blood to get it. Perhaps a slight dose of Caucasian genetics can help strengthen some originally-less-powerful MPB genetics that they already had.)


I'm not totally ruling out an environmental cause. But genetics are still the vast, vast, VAST majority of the problem.
