The best thing you can do is to get a HAIRCHECK test of your scalp which will document all of the hair loss that you can’t see. With this test, you can establish a metric which will allow you to make decisions, such as the use of medications if you are indeed balding. If you start taking medications, you can track your results over a year when you repeat the HAIRCHECK test again.
See here for a good example of this process with photos: https://baldingblog.com/2017/01/10/value-haircheck-bulk-measurements-two-patients-seen-today/
Most likely about to start meds; would appreciate advice from tressless
