I have seen this youtuber nick shell and he has a theory that the hairline you have when you are one is the most likely going to be the hairline you will have at age 35. Now he has some weird theroies about if you have a beard at a young age 16 then you will most likly lose your hair which i do not belive in. But the one year old hairline theory has some truth to it. I looked at my dads one year old photo and he has the exact same hairline as he did then. I then looked at one of my uncles one year old picture he showed a norwood 3 and he is 40 and has a norwood 3 and i have seen anouther one year old picture of my step uncle and he has a norwood 4 to 5 hairline in his one year old pic and he has that hairline now at 40 years old. Guys get a picture of yourself at age one and see how your hairline looks and if you cant find a picture of yourself get someones whos is in thier mid 30's and compare. Would like to see how to true this theory is.
