Hi I have a half full bottle of rogaine that fell to the back of my bathroom cabinet about 4 months ago. I found it today and I was wondering if anyone knew how long it stays effective after being opened? The expiration date is 2/2013. Thanks!
How long does an opened bottle of rogaine stay good for? Thanks!?

I'm sure it's okay to use until it's expiry date even though you have opened the bottle.
