I'm worried because I have thin hair in the parting area.

My hair is on the longer side, so I've been parting it to one side for a long time.

I feel like the hair in that part has thinned out a lot.

I tried changing my parting to the other side, and that side looks a bit sparse too.

I wonder if it looks like this because of the parting.

Or I am wondering if this situation should be considered hair loss. I would also like to know what kind of management or treatment would be best in such a case.
