eSalon custom hair color is very different from "boxed" hair color you find at a drugstore. Whereas boxed color is mass made to fit everyone's hair, eSalon formulates each individual order according to your personal hair details, including gray percentage, coloring history, and more.
eSalon's colorists blend your custom color using over 2,000 pigment options. This means your formula will be highly individualized --- more so than the retail box you may have used in the past. In order to make your transition easier and provide the best outcome, this chart provides an approximate comparison between Clairol's Herbal Essence colors and eSalon's colors.
