Will I bald like my grandpa

My dad is 55 and is still a NW2 with good density, but unfortunately I don’t think I got his hair genes. Looking at my maternal grandfathers pictures I have a really similar hairline to him and the same big forehead. He said he didn’t start losing hair until 40 and was a nw7 around 60. However I think he started earlier than 40 he just didn’t really notice it getting bad until then. I was an NW2...
