Why Test Dutasteride In Korea?

I have been looking into this dutasteride thing and now see that they are conducting tests for male pattern hair loss in korea.

my question is, is it really wise to conduct a test for hair loss in a country like korea? I assume that they are only testing koreans? Koreans dont seem to get as effected by male pattern hair loss as others do. Infact i noticed asians usually have alot thicker hair than most other nationalities (and thast very lucky for them)….

I just thought conducting it in a country like USA or Australia would be smarter since its multicultural so we can see benefits for all ppl. what do u think?

There should not be any racial differences between the way men respond to drugs like dutasteride or finasteride. I asked such a question to Merck, and that was the answer I got. The tests are for safety and effectiveness. Safety includes all types of side effects (for dutasteride this would include impotence, sexual dysfunction, organ dysfunction from any part of the body, interaction with other drugs, and the like). Effectiveness with a classic double blind statistical scientific methodology includes determining the optimum dose to be used and the impact on the target organ (hair re-growth or slowing down hair loss). It is not unusual for tests such as this to be performed in other countries, because costs may be lower.
