I am frequently asked by my male model and headshot clients if they should shave prior to their session. With facial hair being a huge trend right now, I encourage them to do both. Why not show a little more versatility and range in your look. At the end of the day, your headshots and portfolio are all about you showing who you are and your potential for future bookings. So with that said, don't limit yourself!
One of our recent DC actor headshot clients is a great examples of how we can get two very different looks in one session. Check out Thomas below, with and without facial hair.
