Races, Lactose Intolerance, and Hair Loss

Is there a correlation with racial differences in hair loss and the tolerance of lactose in the diferent human races? (https://en.wikipedia.org/wiki/Lactose_intolerance)

Lactose (milk and milk product) intolerance among different races are well known observations in the medical community. There is no correlation with lactose and any hair loss issues in any races. Many races or groups of people have semi-unique genetic differences that reflect diet, for example. Asians generally have a lack of an enzyme called alcohol dehydrogenase which contributes to a ‘quicker’ intoxication when drinking the local brew. On a humorous tone, it has been said that an Asian is a “cheap drunk”, but I personally know plenty of Asians who can easily out-drink me – including one of our editors, Dr. Pak.

Male pattern hair loss is widely considered a genetic trait. However, it does not follow a particular simple Mendelian genetic pattern. In other words, you may be the only bald man in the family. With respect to the male pattern hair loss penetration in different human races or groups it seems to be relatively universal with one exception. There is a small group of North American Indians that are known to not have male pattern hair loss.
