It’s genetic. My dad told me no one on his side is bald, and years later I confirmed it. My gramps had long silver hair and told me back then “you can easily get dates when you have long hair, you stand out.” I said “Really? OK.” That was it for me lol
My parents would not allow me to grow my hair long while I was in high school, and that was back when long hair was in style.
After I graduated, I grew my hair long, as well as growing two inches in height. All of a sudden I was getting a lot of attention from females. Even without any facial hair.
