Is my hair thinning?

I don't no what is going on with my hair. When it's wet it looks really thin, but when dry, it looks and feels thick and full. My hairline has no changes. The issue is that you can see my scalp when my hair is wet and it is freaking me out. I have done every hair loss test from the 60 second hair test to counting hairs lost everyday. Everything points to no hairloss except for my hair being wet. I really need some input on this. I am only 18. A picture with it wet is attached below

This is it dry.

Hard to say on those pictures alone, but basing myself on those pictures alone I'm fairly certain you are diffuse thinning...
Your hairloss reminds me a bit of mine and Exodus's.

What does that mean for me? Years until it's gone? Etc...
