Did Propecia and Creatine Turn My Hair White?

Thanks for your time.
I have been on Propecia for a year. I am in my twenties, and I had seen good results, until i used creatine monohydrate for a month with my workout regimen and it seemed to stop the effect of propecia. this is not my question however. Over the last month on propecia, after i had stopped creatine around 2 months ago, I have noticed that a small area of my hair in the front has begun to turn grey or white. As i said, i am in my twenties and have long-ish black hair. I was merely curious as to if you have heard of this ever happening before? Thanks again.

There is no evidence that I could find that links white hair to either Propecia or to creatine monohydrate.
