No, not fact. Utterly false. I went bald at 17, father went bald at 17, grandfather went bald at 17.
They told me they saw a lot of other 18 years old balding when they were in the army.
And this was in 1980 and 1955. Nothing has changed, baldness is and has always been 100% genetic.
Baldness in young men was as widespread 100 years ago as it is now.
FUE back then was not as common as it is today - FACT!
50 years ago is nothing!
I am talkin centauries an millenias ago.
just because your grandpa saw some young baldies doesn't mean it was as common as it is today, he just noticed them cause he was bald.
it seems your paterlineal line is low on treasure, somewhere a long the line, a fapper spent it all, that's why you deplete your vaults at such a young age and go bald.
