A partial highlight will give a brightening effect using lightener and foil application and will focus on the top and sides of hair. A full highlight will foil the entire head, and is the less-popular option. If you want to see consistent brightness throughout the hair, or you want to wear your hair up and see consistent color, you should schedule a full highlight. If you’re looking for a touch-up or some brightening to the top of your head, schedule a partial highlight. Your stylist will help determine what the best option is.
