I want to color my whole hesd red.. but can I do hi lites too if I colr my whole heard red first?

If I color my hair red, can I do hilites?

Best to talk to a hair dresser about this. Red is not an easy color to cover up, and adding highlights after you dye, could give you bad results. A hair dresser can add the highlights and color the hair, without doing both separately and ruining the look.
