Stopping Rogaine Cold Turkey??

[Mike2013]

I went to Dr and I mentioned since starting rogaine 9.5 months ago, I've lost a lot of hair where previously it was only slightly thinning over years. He said I am just part of the 20% for whom it doesn't work for, and that it wouldn't cause me to lose hair, just that it is not working. He told me to stop for a month and then he will write a script. My understanding was that stopping suddenly could cause another shed? That is the exact thing I am trying to avoid, so I am holding off a bit before I decide what I want to do. Has anyone stopped suddenly and lost hair because of this? I don't think I will lose what I gained- since I never did gain anything but lost a lot (All I really want to do is regain what I've lost since starting Rogain- my hair was nowhere near thin at that time).
Thanks.
