Oh wow that's crazy, the same thing happened to me!
I only tried using it a couple of times, and each time I had a bad allergic reaction, swollen puffy eyes, runny nose, even had a rash on my arms and shoulders.
Needless to say I never used it again.
Of course this does not mean Minoxidil is bad, it's like peanuts, bee stings and Justin Bieber; some people are simply allergic to them.
