Hi LaserCap, thanks for your suggestions! I've stopped Rogaine about two or three years ago already. I had about 7 years of reasonable success, then lost ground. I jumped on Dutasteride and this has done a decent job of maintaining, then phased out Rogaine. I'm very sure that it was having very little effect by the end, so I've no regrets about dropping it. But that's just me, maybe other people might see improvements in combination with different treatments.
However, I'm curious to know what would happen if I now restarted Rogaine after not using it for several years. I'm not sure if this is scientifically accurate, but I've read the effects wear off as the body builds up an immunity to it. So, after three years, would you lose that immunity? Would it start to work again like new?
I've seen a few threads discussing stopping and starting Rogaine after prematurely quitting for whatever reason. But this is a different situation to the one I'm interested in. Would be interested to hear from anyone with a similar experience.
