Minoxidil and propecia first, then wean off minoxidil?

[damnspot]

I've been reading about different hair loss treatments: from what I understand so far the specific action of minoxidil is not properly understood but it has been shown to be effective in regrowing hair. I'm thinking, if after a year or so of minoxidil and propecia usage there has been successful regrowth would it not be possible to preserve that hair with propecia and slowly wean off the minoxidil? Or is the minoxidil superfluous if one is using propecia anyhow? I've read on this forum the opinion that there's no point in introducing both propecia and minoxidil simultaenously, it's better to wait a year with propecia alone to see the results before considering minoxidil. Is this the commonly held view?
