Facial hair loss?

Anyone with experience about this?

        I am 33 years old. About 6 years ago I started losing goatee area facial hair. I never had sideburns which connect to the goatee. I always had a thick mustache, beard and sideburns that grew in well except the "chinstrap" area. Now, it's SO patchy I shave my entire face. My father said that my grandfather had an herbal skin balm from Iran about 50 years ago, (while he was there working for WestingHouse as civilians), and it cured a similar experience he had decades ago. Otherwise, I have found nothing but snake oil out there. Any similar experiences and/or remedies would be appreciated.

      I also believe that when it come to our bodies different ppl have different problems and different resolutions,in turn, I am always willing to listen.
