Multi chromatic coloring is best known as "highlights," lowlights, or dimensional colors. This service can vary from an hour to several hours. Highlights on short to medium hair with one color that create a "natural look" are often completed in an hour. Foil placements throughout the top of the head with multiple colors on short to medium lengths generally require 1 1/2 hours. A full head of foil placements typically requires 2 hours. Longer hair may require more time.
