My hairline is really weird and uneven. It really bothers me. Any way can fix it or make it look better? (photo)

You can add grafts easily to make your hairline more even.  It would be simple and a relatively small procedure.  The grafts would take about a year to grow in.
My first reaction when I saw your hairline, though, was "Wow.  Nice hairline!"  All natural hairlines are uneven, so just be careful not to make it TOO symmetrical, otherwise it will start to look unnatural.

If you are happy with your hairline and want treatment options you should schedule a consultation with a doctor.

You would benefit from a hair transplant preferably advanced FUE hair transplant using DrUGraft techniques. With this approach not only would you avoid a line of scar, your doctor can selectively extract the best mix of hair including finer hairs from the nape area to correct your asymmetry in a most natural looking manner. The indication for your transplant is not hair loss, for which reason, donor supply is not a concern. I expect about 600-800 grafts would fix your situation
