I hear you, Derek.
Some words of advice. First of all, if you are going through a period of hairloss, don't assume that the rate that you are losing your hair right now will continue until you have a horseshoe head. I was an NW2 at 25, thought the sky was falling. I went from a 'normal' hairline to a receeded temples/widows peak look very quickly. The good news was that my hairloss stopped, and I kept the same widows peak hairline until age 34 and after a year or so of first realizing that it stopped, and then getting used to it, by age 26 I realized that despite the receeded hairline I was still getting chicks!.. so I didnt worry about it as much.
Back to the story, at age 34, my center-forehead hair started to thin. Looking in the mirror I could see that if I let this go I would be looking like Phil Collins in a year or so, so I nipped it in the bud, started treatment, and caught it... saved my hairline!
My main point here is that hairloss does not occur all at once, but in stages. Initial shedding, or some recession, is not uncommon and in the big picture might not really hurt your looks much. Some women actually like it. Despite what some people on this website say, I do NOT think that the goal is to have a perfect hairline, but it is more important to have an age-appropriate hairline. And on top of it all, your own personal confidence will make you far more attractive than any effect your hairline will have. I have seen balding guys with confidence score big time at clubs again and again, and unconfident guys with not perfect but pretty f*****g near perfect hairlines sulk around a nightclub and get nothing. You get what I am saying? It is just something to think about. Sometimes the best cure for early male pattern baldness is not medicine, but a committment to hit the gym and build some muscle, and confidence, and just keep your I am who I am and I dont give a f*** attitude.
Now, if you do reach a point where you think that your hairline is not age appropriate and want to start treatment, there are non-internal treatments that do work very well. I also think that a lot of the flack that Propecia gets is unwarranted... it is a very effective chemical and most people have no side effects at all. Propecia, Rogaine, this stuff works. Perhaps you have to make a judgement and contemplate this all for a while?
No matter what you do, there is one element of the "Big 3" hairloss treatments that you can and should start immediately. Next time you are at the grocery store, go pick yourself up some Nizoral shampoo. It is marketed as an anti-dandruff shampoo but its chemical properties help negate the immune response that exacerbates pattern baldness, and the active ingredient in it has also shown to have some ability to fight DHT, the chemical that causes pattern baldness. It is not like Propecia or Minoxidil of course, but it might be just one thing you can easily do now to add a little stability to your scalp. Use it 3-4 times a week, and use your normal shampoos on the other days. When you do use it, apply it and lather it in and let it set for 4-5 minutes (perhaps as you wash the other parts of your body) to let the chemical sit in a bit.
Hope this helps
