Is There a Limit as to How Many Hair Cycles a Man Can Have?

Yes, but the normal, non-balding male’s number of life cycles are not limited. In a balding male, they may be limited in the balding area to between 5-8 depending on the length of the cycle and the age that it kicks in. My grandfather, at the age of 102, had the same hairline as when he was 5 years old.  I suspect, if he did not die then, his hair would have kept growing and growing.
