My maternal grandfather was bald and my father, who’s almost 60, has substantial thinning around his crown and a receded hairline. I just turned 27, and I don’t seem to have much if any thinning. The temples of my hairline have receded an inch or so in the last couple of years but everything else seems to be in place.
How long can my luck hold out? I have plenty of friends my age who have already lost substantial hair but I have not even though I’m certain I’ll lose substantial hair because of genetic inheritance.
As a general rule, you may follow your family pattern not only with balding but with the onset date. When did your dad start balding? You can have your scalp mapped out for miniaturization to see if you have early signs of genetic hair loss, but if you do not see it, I would not even go that far.
