melatonin and hair loss

I’m taking oral melatonin everyday and experiencing hair thinning not sure if it’s because of the oral melatonin of everyday use, would you happen to know if this could be the reason behind it since it’s a hormone pill type of thing? 

There is no clear answer to the relationship between melatonin and hair loss or hair growth. I found references both ways. But you might try stopping it and see what happens.
