God...
You guys are brutal...
Edprush, you are lucky and unfortunate at the same time. Today, more treatments exist for treating thinning hair, but none of them is a panacea.
I've had thinning hair for about 8 years. I've fought it and had moderate success. Unfortunately, moderate is about all you can hope for, but there are some great treatments on the horizon. Some are already available outside the US, and the others should be available within 2-5 years, after FDA approval.
To sum it up...
Rogaine - I call this "bad hair in a bottle". Minoxodil (sp?) in an alcohol solution. What happens why you put alcohol on something? It dries it up, and therefore leaves it difficult to maintain. Its results are very limited, and less than 50% of people actually respond to it. Plus it only helps in the crown or "bald spot" area, people who are losing hair up front get no gain from it.
Propecia - A man only pill, right now it is the best drug currently "on the market", though there are better ones that are not approved yet. Propecia is pricey, about 50$ a month, however, it in my opinion is worth it. It won't grow a ton of hair back, but it will at least slow you loss, and in some cases stop and reverse it all together. Propecia with Neutrogena shampoo is the best thing out right now, but you do need a prescription.
???? - There is a drug on the horizon that has had *AMAZING* results with hair regrowth, however, it is in fact a high blood pressure treatment medicine. Somehow, as a side effect, it sponsors massive hair regrowth (I don't know if that includes like palms-of-hands and backs or what). Recently talking to my doctor (since you need a prescription for propecia) he talked about it, but he wouldn't even tell me the name, for fear of a 'black-market' on the drug. What he said is that they are working finding out if they can separate the blood pressure part and the hair growth part. Taking high blood pressure medication when you don't have high blood pressure is a no-no, so don't expect this drug on the market until they can figure out what is going on. 2-5 yrs away on this one.
The two other options are medical hair replacement and non-medical 'rugs'. These are decisions you have to come to late in the game.
My suggestion is use propecia/neutrogena. Stick it out until the 'miracle' drug gets approved and becomes available. I stay keen on the issues since baldness is in my family, and fighting it early makes more sense than paying lots of money later on for treatments. Good Luck!
