Some tips for highlighting brunette hair include selecting and buying the right highlighting kit and getting all the materials needed for the procedure ready. Before highlighting brunette hair, determine how much hair to highlight and whether to highlight the hair all over or just certain strands.
Use the kit as per the manufacturer's instructions. Most kits come with a spatula for application of the product, although a toothbrush is a good substitute. Use an adult toothbrush for front sections and a baby toothbrush for back sections.
For subtle highlights meant to frame the face, start by parting the hair as usual, and then choose which strands to highlight. Pull the rest of the hair back from the face. To achieve desired results and avoid any surprises, begin with a strand test on a well-hidden section of hair.
