I sweat alot. It's summertime in Florida. I've tryed hats, I've even tryed the "sweat gutr" but I feel like the Rogaine is sweating off my hair and scalp and down my face. It doesn't irritate my eyes but I notice a new taste in my mouth that I can only assume is the Rogaine. Is this something I should be concerned about? The people on the other end of the 800 number couldn't(or wouldn't divulge) offer info.
