Is the hairloss gene dominant or recessive?

[Autumn Sundown]

I had always thought you had about a 50% chance of inheritting it if you had hairloss on one side of your family and none at all on the other. Someone told me that it's more like 80% if you have it anywhere in your family, that doesn't sound right to me but I would like some more insight.
Another question: If, for example, both sides of your family tend to eventually end up at NW6 and one side starts balding in their 20's while the other side doesn't start until their 50's, which one are you more likely to inherit?

Balding genetics are not that easy.
This is not a Mendelian example of white and green peas, there are many genes involved and possibly external causes

That all depends on exactly what type(s) of hair loss you're talking about. The traditional horseshoe baldness seen from sensitivity to DHT is from your mother's side on the X chromosome so you don't have to worry about getting it from your father (unless you're female). However there are many other sources for hair loss that can be obtained from genes on either side of your family that all have their own relative strengths of expression.
