Balding genes can be really unpredictable sometimes. I've read stories on here before where some men can become a Norwood 7 in the twenty's with extremely minimal balding genes from both sides of the family, and some keep their Norwood 1 hair into very old age with balding genes rampant on both sides of the family. We still don't have the technology today to determine 100% if balding will happen to the individual or not before the genetic condition even starts.
