Are Professional Headshots Worth It?

[Cody Gentry]

I was going through some of the profiles on here and noticed that quite a few people have some type of professional headshot of themselves done, so it got me thinking. 

1. In your opinion, Is it worth it?
2. Do you use a professional headshot for social media? (facebook, etc)
3. If you did get pictures taken, how much did it cost you?

Thanks for the help!
