Hair and makeup is totally up to you when it comes to business portraits. The one note we like to give is that you want to present yourself as you normally would on a day to day basis in whichever field your career is in. That means if you don't normally wear heavy makeup throughout your day, then maybe you should stick to a regular level of makeup for your session. We always encourage embracing your natural beauty at Glass Darkly so if you don't want to wear any makeup at all we think that's great! Whatever makes you feel the most comfortable for your session.
