That is interesting DLMI (you have a long screename).
Insulin may definietly be a factor in how blasted OILY western scalps are too. I mean you can take the soya, rice sterols, and green tea catechins away from Asiatic diets and presuppose their will be earlier hairloss, BUT the acne I see on Asian males here in the west is every bit as bad as what the white kids have.
I seen an Asian guy in his late teens working at McDonalds here, and he was tall, fat, with a face full of zits man. His face was oily and had a shine too it. I dont think they were known for much acne at all back east until after WW2.
I see these NO_SHAMPOO nitwits who have convinced themselves that the uptick in male baldness is due to excessive shampoo usage when the increase in baldness and baldness and acne hitting younger people is probably the result of our 'synthetic' dietary habits via excessive androgenic actions that they will cause.
People are bound to react emotionally when they are getting bald at 20 while they still have some acne on their faces. They feel like they never got to have "a prime" in life when their faces cleared up and they still had their hair. No wonder some lash out and look for culprits everywhere except for the correct place for the earlier ages that baldness is hitting young men and the later ages that acne is affecting both men and women--------sugar and starch and high fructose corn syrup and processed food/gunk/stuffs.
