No sides= finasteride not working (Not true)

So I’ve been on fin 1mg MWF for about 4 months now. I’ve had zero side effects whatsoever, which I was not expecting. And I haven’t seen any improvements in my hair so far. In fact, it has possibly gotten worse. Do no sides mean the drug isn’t working?

Finasteride almost always works to slow, stop or reverse hair loss.  Slowing it is hard to see if you are undergoing rapid hair loss.  If you stop the drug, which I am not recommending, you might see the value of it be accelerating your air loss
