Not Seeing Propecia Benefits After Starting Creatine

thanks for your time.
I am a twenty year old male and I have been on Propecia for about 15 months. Around the 8th or 9th month the drug seemed to be working well, for i noticed much less hair loss. Yet also around that time, i began to take creatine monohydrate, and i saw a decrease in the effectiveness of the Propecia. I was on the creatine for 3 months, and after i noticed its negative effects, i immediately stopped taking it. Now, on my fifteenth month, I am not seeing much effect from Propecia as i did 6 months ago. My question to you regarding my real concern is if the Propecia will gain effectiveness in the next months, if ever? Or have I harmed my chances of regrowth with the taking of the creatine monohydrate?

You may have harmed your hair. Propecia will not pick up the pieces here and save you, but you will now have a new baseline to go from. So yes, Propecia should gain effectiveness in the coming months from your new baseline. I have discussed creatine before (see Creatine and Hair Loss).
