Basically you have a few choices.  You can have your hair or makeup done professionally at a salon before arriving to your shoot.  You can hire an MUA, hairstylist or both and have them present at the shoot.  Or you can do them yourself.  If looking to hire someone to attend the shoot I can provide recommendations.  If doing your own makeup please do some web searches on “how to apply makeup for photoshoots” as this makeup is generally applied heavier.
