When your only wish is to see your blond highlights go away, you have two options. You can let your highlights grow out over the next several months or you can take immediate action to remove blond highlights with a quick color application. Covering over highlights with hair color is the easiest, most efficient way to remove unwanted highlights. However, aftercare is needed to ensure that the color does not fade out quickly.
Pour 2 oz. of color and 2 oz. of 10-volume developer into the color bottle, screw on the lid and shake to mix. Put on latex or plastic gloves to protect your hands and skin during the application process.
Apply color to clean, dry hair from root to tip by squeezing a generous amount of color onto small sections of hair and working the color in with your hands and fingers. Apply color until all of the hair has been thoroughly saturated. Check the hair for any dry spots or areas where the color application is thin. Apply color to any area that needs it. Mix up additional color as necessary. Set a timer for 20 minutes.
Rinse the hair completely with warm water. Shampoo and condition the hair. Towel dry, and proceed with styling.
