Brown dye over blue hair is a popular style choice. The color contrast creates a cool look, while the brown dye adds depth to the blue hair. If you are thinking about dyeing your hair blue, you should consider trying a brown dye first. You can use brown dye instead of permanent blue colors to create a subtle, natural color effect. Brown dye can be used to highlight blue hair because it is warm and dark. It also helps blend blue and gray hair. Brown dye can be used on all types of hair, including blonde, red and gray hair.
Brown dye works best if you wash your hair two weeks before you apply the color. If you are using a fade-resistant formula, wait six weeks before coloring your hair again.
Apply the dye evenly to your hair from roots to ends. Leave it on for six hours or overnight for best results. Then shampoo your hair to remove any excess product from the strands.
