TLDR  Indian men have 62.1% hair loss, mostly grade II vertex, and less extensive than other populations.   
  This study examined the patterns of androgenetic alopecia (AGA) in Indian men and found that AGA was present in 62.1% of the male population, with the most common pattern being grade II vertex. The study also found that the balding pattern in Indian males was less extensive than in other populations. The study suggests that further research is needed to understand the genetic and environmental factors that contribute to AGA in Indian men.
