I have very fine hair, can it be fixed?

I’m 22 and was looking through my old photos. I noticed even as a kid, I had a high uneven hair line. I was also looking at my photos from about 4 years ago, when I first noticed that I couldnt spike my hair up anymore due to my hair thinning on my crown (so the hair on my crown would just fall or not even go up in the first place when I tried spiking it).

The thing is, my hairline is still pretty much the same (maybe a tiny bit higher, but it could just be from maturing). My crown is also maybe about the same, but possibly just a little bit thinner. I can see my scalp through my hair and especially when I use flash, but again its not really that much worse than 4-5 years ago.

It just feels like after 4-5 years it would be more progressed if it is balding.

Is it possible to just have naturally thin hair without actually balding?

Men have hair thicknesses from very fine to coarse. You can inherit very fine hair and have a normal see-through appearance rather than the full look of the coarse haired individual. There are hair thickeners that you can use to make your hair look fuller. Speak with your stylist for the best ones.
