Hi Dr. Rassman,
here’s my question is it possible to have the same genetics for hair loss as say your father but not have it to the same degree. For example thinning in the crown but not as much, or recession but not as far back. I have this in families where it is obvious that brothers have the same genes but seem to have less progression of hair loss. I have even seen this where the older brother has more hair then a sibling two to three years younger.
The one-to-one relationship you are looking for does not exist. It is possible that you inherited the gene from your dad, but the expression of the gene might keep you from ever balding. That gene could be passed to your son and he might have your father’s hair loss pattern.
We do note that if you are balding like your father, then the gene may be similar and the pattern of balding you inherit may be the same as his.
