Lowering the hairline would substantially improve overall harmony in my opinion, finasteride won't achieve that.
You may consider some filler for your facial asymmetry, I got radiesse to lower one gonial angle and wider and center the chin, it worked quite well.
Your lower eyelids seem to droop a little and you lack volume below the eyes. Easiest go-to would be just getting filler. Implants + lower eyelid retraction repair may be ideal.
Hairline is the most important issue in my opinion, because it very much highlights the vertically deficient mandible as a result of its impact on overall harmony.
