Headshot makeup can differ from other more "glam" makeup opportunities in that you are aiming for an enhanced natural look. It is very important that you still look like....well, YOU!

In the days leading up to your session get plenty of sleep (especially the night before), drink plenty of water, moisturize (use sunscreen during the day), and avoid too much time in the sun. All of these things will help your skin look it's best. 

Feel free to bring along a lint free cloth to blot out shine or reapply a matte powder. 

Use products in your hair for hold (or humidity/frizz) depending on the weather. Products that add shine (without a wet look) are useful as well. Biosilk is a great serum for shine.
