My husband didn't even start thinning until his mid-50s. That really hurts, seeing your son losing hair while you've maintained yours till much later in life. Same for me--my hair loss started a little over three years ago. I'm not going to lie: I am not handling Androgenetic Alopecia well, but when my son told me he was losing hair, I cried, literally. My father said he started losing his hair around 20. Growing up, I remember him having thin hair on top. When he died at 66, he was pretty much NW6. I never thought anything of it, like everyone else who is somewhat oblivious to others' baldness till it happens to him/her. My father-in-law died at 49. I never knew him, but I've seen pictures of him as a NW6. My husband said he was that way since his early 20s. Baldness runs on both sides of our families, so I can only hope that my son will at least take after my father and keep some hair on top till middle age. Unfortunately, my son cannot grow a beard, although some of you guys have said you had that problem till maybe you were into your 20s. That gives me hope. He's also 120 lbs. soaking wet! I'm hoping his face and body will fill out as he gets older (he has no interest in eating more). Are you still taking Propecia? Did it help at all?
