1. I'm not nw7 but in person I'm still noticeably, visibly balding. I don't look 'normal'. However I wouldn't need more than very modest regrowth from fin to be able to disguise my balding, at least anyone who sees my hair dry.
2. I will never use that harmful stuff. I don't want my face aged or my heart damaged. Also, you need to use minox for LIFE, or all of your DhT sensitive hairs that have become dependent on minoxidil DIE, the whole lot. The Regaine cans I've seen say don't take if you are over 49, so minoxidil must prevent you from keeping your hair long term.
4. I'm not convinced that any slowness or stoppage of loss really says much, it could be a coincidence. My loss was slow anyway, it took me until 30 to see it. The only signs I have of fin working are the loss of itch and less regular shedding, although I had lots of shedding early on which I've not recovered from.
