I See No Thinning, But I Can See My Scalp in Sunlight

Worried about “shiny” scalp.

I have very very fine, wispy dirty blonde hair. However, in the sunlight, very often when I walk past a window I feel like I see so much scalp. I have an intact frontal hairline with a low-dipping widow’s peak and lose next to no hair in my brush or in the shower. The distribution of hair *feels* the same all over.

Does this just sound like paranoia? (I won’t go into the genetics question as that’s impossible to answer).

Yes, it sounds like paranoia. Many thin haired blonds have a see-through appearance where almost anyone can see their scalp in bright sunlight… especially if your hair is wet or is very fine and wispy as you describe.
