no that's a mystery mature is in the eye of the beholder obviously if you think that you're prematurely losing your hair just like prematurely gray right so there's a spectrum some people go gray in their 20s some people go gray in their 80s some people never go gray so how quickly you go gray is genetically predetermined if 70 is the new 50 then maybe you don't want to be gray at 70 so hair loss is very much the same thing
