Similar situation here. Round half of the people I talk to say that I look a lot like my dad, and the other half says that I kinda look like my mum. Dad's a Norwood -1 at 53 with godlike hair genetics. He has very little body hair, I've more than him so maybe that could mean something about how strong my DHT or my sensitivity towards DHT is.
Can empathize with this. This is a situation I wouldn't want to be in and it would probably be the hardest part of going bald for me, since literally the only living bald man in my whole family is my 91 year old granduncle. My maternal grandfather was quite bald (A thin NW4A or a dense NW5A from the pics of him I've seen at that age) but died at 68 while I was a toddler.
So I disagree with the ''it comes from your dad'' idea. From what I've read hair loss can come from either side of the family and even skip generations. Some suggest that the paternal family may determine the 5-Alpha-Reductase activity and overall DHT levels, while your mum's side may be the one who determines your follicles' overall sensitivity to DHT. Often when one side has male pattern baldness and the other doesn't the children will have milder or slower hair loss.
Sadly it seems that the poll doesn't have a ''My dad has a full head of hair and I have mild hair loss'' option so I can't answer it. For the record, my paternal family has godlike hair genetics and I was always assured that I'd never go bald. There's only a bald great grandpa (My paternal grandpa's dad) who balded noticeably in his late 30's, early 40's I think? My paternal grandpa died at 88 with Bill Clinton hair. My other great grandpa (Paternal Grandma's dad) died at 102 with a slightly thin NW1. He was 3/4 Native American. My dad is a barely greying Norwood-1 at 53 and my uncle is a NW1 at 48 with unnoticable crown thinning that may have happened due to strong acne meds since he suffered from severe acne as a teen.
On the other hand, my maternal grandpa started balding somewhere in his 30s and had noticeable hair loss by the time he was in his mid 40s. Ended up as a thin NW4A or a dense NW5A at 68, when he died. My maternal grandma's genetics are even worse: She had thin, wispy hair in her 70s and all of her brothers hit NW5A/NW6 by their 40s or 50s. One of her brothers, my 91 great uncle with whom I talk regularly told me that he noticed hair loss when he was 28 or so and decided to start looking for a treatment when he was 32-33. By the time he got married at 36 he was a NW3A and ended up as a NW4A in his 40s. Funnily enough his son is 44 and has a dense NW2. My great uncle says he used to have his hair before he went bald. My mum has good hair for her age, my aunt has unruly hair and is pretty grey but I think that had more to do with the strong meds she's been taking regularly for decades.
