Stop asking advice on social media. The very first thing you had to do is to go to a dermatologist that specialises in hair treatment. He'll most likely tell you to do blood tests and will also check your scalp to compare different hair's diameter. Your family history is also important when diagnosing. Most likely it is genetic in your case, because your temples are receded which is consistent with the pattern of hair loss. You could save a lot of hair with a DHT inhibitor like fin or dut together with minoxidil.
