Hair Changing Color

[barnaby]

I have been using Finpecia 1mg and Kirkland Minoxidil Foam for over 1 year now and I am 33. I am noticing a decent amount of regrowth. But I am also noticing that my hair is changing color. Not just the new hair on my crown and hair line, but the hair all over my head. I have naturally red hair and the new color of the hairs are dark brown - almost black. Has anyone had this experience before? Anything I can do? I'm also on Wellbutrin and Zoloft - not sure if they can have any effect on hair color.
