I’m a few years older than you but have been on hair loss boards for years. My opinion…stay on medical treatment (fin min niz) and forget about it. You have a good hairline and overall head of hair for 32.
if you want to be adventurous you can add dermarolling once a week but the jury is still out on that one.
you have far too much hair for a transplant and it would be too much risk for minimum reward. Even if your transplant is successful, chances are only you would notice it
