I does not matter one whit what we might "approve" or "disapprove", (and, in fact, this crowd is not the "disapproving type). What matters is that you feel good about yourself -THAT is what we all want for you!
If you think that you need to try the rogaine, and if you are willing to accept the possible consequences, then you should do it. We will be supportive of whatever you do. Just keept in touch please.
And at least you now know that if, ultimately, your hair loss progresses, that you have an alternative and that you will look great if do go sly - the photos prove you look really good with the sly look!
So, all in all, I think that your experiment has been a win-win for you!
