What is the % of white men that eventually go completely bald, and partly the worry about the male baldness is my son’s best friend is almost completely bald with very thin follicles on top at age 27, how young does one start to experience MPB to have this stage of loss by age 27, he’s literally NW 6 1/2 if that’s on the Norwood scale

The statistics are that about 45% of men will have some clinical balding by the time they are 45. I have seen the process start at 16 years old and some reports have placed it as early as 12 years old. Most of the really bald men see some sign of balding by the time they are 21 (clearly evident on high magnification views with miniaturized hairs with thin shafts). The real question still unanswered is can this all be stopped when the advanced balding young men start Propecia early enough. At the age of 27, the pattern in the man you are talking about will probably be a Norwood Class 7 balding pattern. Class 7 on the Norwood scale.
