MacDruid, I am one of the people who threw around that comment. But, you have to keep in mind that my male pattern baldness is probably a bit more advanced than most. My temples, I had written them off years ago... so the fact that I have taken three-quarters of an inch of the tops of them is a GREAT thing. I can live with a 'widow's peak' hairline, I just wanted to save my center-forehead hair, that narrow patch of hair between my temples that started to thin badly, which would have left me with a nice horseshoe.
My regimen has completely reversed this. My center forehead hair is growing long and strong, amazingly so! Even though it is not 'regrowth', it is a godsend for me in terms of cosmetic styleability. Sometimes, improvement of existing hair actually exceeds my expectations in terms of my 'total look' than I had going into my treatment when I was thinking of a possible serious hairline lowering. I look great! I don't mean that in an arrogant way, but, I am just saying that the thickening of my existing hair has made a more of a cosmetic improvement for me overall than I could ever have dreamed of.
Now, if you are younger in your male pattern baldness experience, then perhaps your experience will be different. Catching it earlier means that your follicles have had less time to degenerate, and you have had less time to 'get used to' having a 'high forehead' so to speak.
In a nutshell, our minoxidil or regimen experiences will differ from person to person. You can't take the particulars of what one person says is 'good response, but modest hairline recovery' as a rule for all. The earlier you catch it, the earlier you can improve it... minoxidil, statistically speaking, will improve your hairline. What, exactly, that means for you depends more on your starting point than your ending point.
Cheers! Gard
