I did. Many people get annoyed I noticed their hair loss, even when it is obvious. They think I'm putting them down, or they are angry I am giving them unsolicited advice. And if they get any side effects, they will come back and try to rip your head off. Sad but true. My brother is the only person who took my advice and wanted to save his hair, but even he gets upset if I ever say he needs his hair. He wants to believe hair does not matter, and hear that from me, but also is willing to spend a lot of money on any possible cure I tell him about. And his is the best response I got from anyone. The rest were negative, or they said they don't care about it. If you have people skills and can get the word out without offending people, then keep it up. I'm not too good at it though.
