I have been on minoxidil and finasteride for over a year and now am shedding very fast

Is there a way to tell the difference between a standard min/fin shed cycle and min/fin no longer being effective? I’ve lost a ton in the past 3-4 weeks after being on fin and min for over 14 months, and am terrified min/fin are no longer effective and that this shedding won’t stop.

If you have been on finasteride and minoxidil for 14 months are are now seeing shedding, you most likely are experiencing an acceleration of your balding. You might want to see your doctor and get an opinion. If you were my patient, I would have had a HAIRCHECK test done on you a year ago and would repeat the test to confirm new hair loss and to what degree. That is the value of the HAIRCHECK test when you start treatment.
