Did you hear that correctly? Shave your face before you come in for Headshots!! If you don't shave, you will look stubbly and it's not going to look good. It's extremely difficult to remove stubble in Photoshop, and it usually winds up looking very fake.
Remember that the better you look in real life, the better your picture will look. This means you should try to use makeup to cover blemishes instead of doing it in post. It also means you should shave.
Not shaving before your headshot session is the same thing as coming in to take pictures and purposefully making stupid faces. Why would you want your pictures to come out bad because you were either too lazy or not thinking at all about what to do beforehand?
Shave before your headshot session, and you'll be much better off. Unless of course you want to have a beard or stubble in your shots.
