Whenever you look different. That is to say... Whenever you change permanently from the way you headshot looked in the past. Basically the easiest way to put it is this:
If you can't change your look before going to an audition to make yourself look the same as you do in your headshot, then you need a new one.
For children, this might be every six months. For teenagers it might be every year. And for adults it might be every two or three years. I definitely don't recommend getting headshots less frequently than every three years though because of changing industry trends. Imagine if you still had a black and white headshot? Uh oh! That's a big no no.
There are tons of little things that are constantly changing, and keeping your headshots updated with the current trends will brand you as professional. Don't expect to get an acting role with an outdated headshot.
