It is very important to arrive with finished hair and make-up.  The extra effort is worth it.  Small imperfections are more noticeable in a photo.  Makeup photographs approximately 2 shades lighter so wear a little more than you would normally wear.  It is recommended that you cut and/or color your hair the day of your photo session.  One week prior is a good rule of thumb.  A hair and make-up artist can be provided through Kristin Smith Photography for a minimal fee.
