rogaine

Rogaine have invented an amazing product and marketing strategy. You take it to prevent hair-loss. You have to start it before you go bald though. So you have a large percentage of men using it that aren't going to go bald at all, but are forking out $39.99 per month on the product. For them it appears to be working. Their hair isn't falling out. And that's the other part - you have to keep taking it. If you stop, your 'new' hair will fall out. Geniuses. I want to invent something like that.
