Well, seeing that he even put as acetaminophen , I really don't think it is serios list, basically, he mention almost any drug even fluoxetine ! that is a well know safe drug and there are theories that the high sexual side effects is because it lower DHT levels. And even cetirizine ! that is a big LOL : A preliminary study on topical cetirizine in the therapeutic management of androgenetic alopecia. :https://www.ncbi.nlm.nih.gov/pubmed/28604133
Anyway even if we believe this list where is almost is telling you that water can cause hair loss, it will be telogen effluvium, not androgenetic alopecia.
But don't worry, trazodone will not cause you hair loss.
Do you regret to had taken propecia?
