If you don't have thyroid issues or any other medical issues, you need to accept that it is very common for some men to start losing hair in their 40's. You have only one option. Take finasteride( with minoxidil if you want the best combo treatment) or just accept your aging better than alot of guys your peers but you don't have hair genetics that will make you immune to balding like Patrick Dempsy, Ronald Reagan, Joel Osteen, and Ed Quinn. You should have been bold enough to show your hairline pulled back to show you are receding. On top of that showed your hair wet so we can see if you have a balding pattern. My hair looks horrible wet but dry it looks fine in photos but I have lost alot of density mostly in my 40's.
