Yeah, I have two issues with this post.
First, you're assuming that the only reason anyone would ever want to fight hair loss is to attract women. Maybe I'm in the minority here, but I'm fighting hair loss because I don't like the way that I would look bald, not because of what anyone else would think of me. It's about ME ME ME.
Second, you assume that you would only want to fight hair loss if you are insecure about your baldness. I disagree. If you want a raise, does this mean that you are insecure about your current salary? Not necessarily. As human beings, we instinctively want MORE MORE MORE, this doesn't mean that we're insecure with what we already have.
