I'm scared I have DUPA. If I do is there any hope?

I took flash pictures of my sides today and I realized that they actually look quite thin. My paternal grandfather appears to have very thin donor hair so this wouldn't have come from nowhere.

Here is an album of my hair:

Without a flash I don't think it looks too bad but with a flash it's scary.

Right now I'm just on fin and I'm waiting to see how it goes for at least 6 months before I add more things to my regimen. If I have DUPA I might be screwed regardless.

You're freaking out, dude. You don't even look like you have hair loss, much less DUPA. Anyone with a shortish hair cut will show some scalp with a flash photo. Stay on the fin and relax.
