Hey oms,
It's very easy to get pessimistic when it comes to the hair issue. For about six years I've been on an emotional rollercoaster. I have gone through every scenario and came up with a conclusion that worked for me. I'll be 30 next month and just had my first transplant 3 months ago. I realize that I will never have the hairline or density I had at 20, but I'm not 20 anymore. It's a fact of life that we all getting older and our bodies change. What I came away with is that I wanted to be proactive in dealing with this issue and the right coarse of action for me was to get a transplant. I'll probably need a couple more, but at least I'll know that my hair will look decent for a very long time. And if I need a few touch ups here and there, then so be it.

I understand where you are coming from, but are you also going to stop working out, become obese, waste you life away on the couch etc... after all we are just going to turn 85 or so and die anyway. What the point to a healthy life? To me it's about the quality of life not just the end result.
There is no perfect solution for our dilemma just yet, but I believe most of us have come away from this HT experience feeling much better knowing that we are taking matters into our own hands. It's not for everyone, but I didn't want to lose all of my hair. Others feel great about shaving their heads or just letting nature take it's coarse. You'll eventually find what's right for you.
By the way I'm almost 30 and just starting to peak. I'm single, financially stable, and in the best shape of my life - and this weekend I went out to a club and walked away with two phone numbers! Life doesn't end here for me, I just look up to the "Cool Guys" who are still peaking like Brad Pitt, George Clooney, Mel Gibson, John Travolta, Nic Cage ... and they're all over 40! (Pitt's 39) and from what I hear at least one of them has had an HT.
We are all on your side here and we have all gotten down on ourselves about this whole experience at one point or another. But there is light at the end of the tunnel. Hopefully this experience will make you stronger no matter what action you choose. Who knows how we will all look back on this, but hopefully we'll all come out better people for breaking through this rough time.
Hope this helps!
