Do i have diffuse thinning or am i overthinking?

hey guys, so i actually wanted to grow my hair out, but decided to get a buzzcut first (idk i just felt like it)

ive been wondering sometimes if i could be thinning, so i thought ill show you. im 20 now. i think my hair was never the densest but idk

if im just overthinking.

NOTE: the first pic is from two years ago, as comparison. the other pics were all taken this week.

the last picture is from the evening right before the cut

idont shed a lot if hair

The bald spot at my hairline is a scar

thx for any help :slight_smile:

go see a dermatologist. nobody can diagnose you as better as him/her. pick one with a trichoscopy equipment.
