There's a kernel of truth to the maternal myth: one important hair-loss gene sits on the X chromosome, which men get from their mother. But research shows pattern baldness is polygenic — influenced by many genes inherited from both parents, not a single maternal one. So a bald father raises your risk too, and you can inherit a strong tendency even if your maternal grandfather kept his hair.
Practically, look at relatives on both sides for a rough sense of your risk and likely pattern, but treat it as a tendency, not a destiny. Genetics loads the gun, but the timing and extent vary, and proven treatments can change the outcome. If close relatives on either side lost hair early, that's a reason to monitor and act early.

FAQ
If my dad isn't bald, will I keep my hair?
Not guaranteed — you inherit hair-loss genes from both parents, so you could still thin even with a non-bald father. Check your mother's side too, and watch for early signs.
Can I predict my baldness from relatives?
Only roughly. Family history on both sides hints at your risk and pattern, but it's a tendency, not a precise forecast. A self-check tracks your actual progression better than predictions.
