24 and pretty much already bald.

[cdub]

I am 24 pretty much already bald.

Attached are a few photos. It should be fairly obvious which one is which. The one with more hair is me 3 years ago. Right now my hair is really long, if I cut it it'll be significantly worse.

I don't really know what to do. I tried a few shampoos and topical sprays recently, but I don't really have faith that anything will happen after spending all that money. Even on this forum, is something like this normal?

I don't know what happened. I may not work out, but I'm not overweight and my diet is fairly decent. My dad is in his 40's with all of my hair, and his dad's dad (now in his 90's and still going) has more hair than he does somehow.

I may try to see the doctor soon in case it is a sign of something really bad, but I just wanted to hear from some other people first.
