Climbing the Genetic Hair Loss Tree

My mom’s dad was mostly bald by 30, but my dad has absolutely no sign of baldness at 56 and his dad had a fair amount of hair left in his late 70’s.

I know your mother’s father is the best indicator for inheriting MPB, but what if there’s an extra Y chromosome involved (i.e. someone who is XYY)?

Since I inherited my dad’s hair twice (it also become brown and then later curly at the same point in life, 11 and 17 respectively), could I have dodged a bullet?

I’m closing in on 21 with no sign of baldness yet. Would the extra Y outweigh the MPB on the X chromosome?

Thanks

Even if you were an XY, you have about a 50% chance of inheriting your father’s family line. I do know now about XYY like you are, but I would generally tell you to do what I always tell people to do when determining their likelihood of developing genetic balding:

1. Get a genetic test from HairDX
2. Follow your hair looking for both gross and microscopic changes in potential miniaturization. This is the practical side of the process and it is easy to do this type of microscopic evaluation by mapping out your head for miniaturization.
