don't forget that the more advertising you see for something, the less people are doing it. Why would the companies be paying for the advertising if they had enough business? they are trying to reel in men with MPB because the trend nowadays is to just shave it down and get on with life, which is taking money out of the hair restoration peoples wallets. Their trying to keep the idea that if your balding the accepted and right thing to do is have someone hack into your head and transplant some hairs, as if thats going to make everything okay. No thanks.
And if a legitimate cure showed up that didn't have crazy side affects, yeah a ton of people would opt for it, if given the choice I think a lot of people would go back to hair, since it was taken from them against their will in the first place. I would, I enjoyed my full head of hair when I had it. But a legitimate cure may never show up, and definitely wont in the next 10 years, so I'd embrace the baldness.
