Is there any correlation between ethnicity and hairloss?

Im surprised to read that Caucasians have the highest incidents of MPB, when I look around in my surroundings I find middle-easterns have the highest incidents of MPB.

Well, Middle-easterners are, anthropologically, the same race as Europeans. It is still my understanding that Europeans are slightly more prone to MPB than are Middle-easterners. Greek and Macedonian men are believed to have the highest incidence of all. Men from the Nordic countries also have a very high incidence.

The reason for ethnic differences in proneness to baldness is, of course, genetics. More specifically, ethnic differences exist in the level of genetic sensitivity of the scalp hair follicles to DHT. Caucasians have the genes for androgen sensitivity, whereas Native Americans have the genes for androgen resistance.
