Pass down to brother? male pattern baldness

[Relient2]

So male pattern baldness hit me when I turned 19 and is still going after me no when im alsost 21. My dad also recently within the last couple of months has been thining at the age of 50 which is weird because he started losing his around the same time I starting losing my hair... sept he got to keep his 30 years longer lol
But I have a little brother who is 15 what are the chances that this is going to strike him as well ?\
thanks a bunch

I started to lose my hair about 3 years ago. I have a younger brother who is a year younger than me and he doesn't have a problem with his hair... yet.

I have a brother who's a year older, but the bastard has more hair than I do. His baldness seems to be just localized in the temples. I got the receding hairline, loss of temples and diffuse thinning..... and I'm the younger one dammit!

I guess the point is, siblings aren't guaranteed to share the same baldness gene... so it's hard to say when your bro will start going bald or if he ever will go bald

my brother is starting to as well, at age 19. i can see his hairline beginning to weaken and some diffusion behind it.

i have an older brother who is 24 and has lost much more hair than me...he isnt on any treatments however

I am 23...and my hairloss isnt really noticeable to others...Ive been on treatments for 7 months

I have a younger brother who is 18 and he has vertex thinning already...he started earlier than my older brother than I.
