Oh gods, this, again???
Noir summed it up perfectly - ALL hair has a terminal length, otherwise the hair on your legs, arms, privates, eyelashes and eyebrows would be as long as the hair on your head - and that's not the case.
Terminal Length = Inch Rate of Growth * Time Length of Growth Phase, very simply.
Very few people ever reach terminal length on their heads, though, for the simple reason that most people don't take immaculate care of their hair for 5-7+ years - and thus breakage and trims/cutting conceals the actual terminal length.
And it's very hard to 'guess' at your terminal length, because it's almost impossible to determine what the length of your growth phase is, and depending on your health/diet, I think that it can actually vary.
That's what makes the caffeine thing so interesting - the studies indicate that it extends your growth phase by 37%, which means it adds 37% more hair to your 'set' terminal time.
