Your headshot should be an accurate representation of what you look like on a fairly regular basis, so your hair style should be one that you can easily achieve on your own. Because of this, hiring a hair stylist for your headshots shoot is probably unnecessary. However, you need to make sure your hair is presented in a way that doesn’t distract the viewer. If you normally have unkempt or unruly hair, you should have it properly cared for (cut and styled) well in advance of your photo shoot.
