Make an honest inspection of your hair. Does your color need refreshing, or do your roots need a touch up? Schedule color three or four days prior to your shoot to allow time for settling. Consider having your stylist apply a shine treatment, as shiny hair equals healthy hair, at least in appearance. Avoid any drastic, or medical skin treatments prior to your shoot, instead use plenty of moisturizer and good ex foliations at least twice in the before your shoot.
