Every eSalon hair color order includes Personalized Instructions unique to your custom color. They include a detailed explanation of how to apply your color at home and are crafted specifically by your Colorist to achieve your current color goal. That means they may change from order to order, so it's super important to read them carefully before applying your color. Common missteps such as leaving the color on longer than instructed or washing the color out before it has fully processed can result in a look you might not have been going for. So read 'em, read 'em, read 'em—every time you color.
