Colouring your hair to change or enhance your existing colour is typically a pleasurable experience. But if your at-home or salon hair-colour change has left you with less-than-satisfying results, you may not want to live with the colour until it grows out. While removing artificial colour from your hair can add stress to already-processed hair, you can at least accomplish the job at home rather than spend more money at the salon.
Wet your hair with water. Mix 1 tbsp clarifying shampoo and 1 tsp dish soap in the palm of your hand. Lather up your wet hair with the shampoo-and-soap mixture. Rinse your hair thoroughly then wash it a second time with the shampoo-and-soap solution.
Rinse your hair a second time with warm water, this time continuing to flush your hair for a few minutes to further help remove the artificial hair colour.
Treat your hair to a hot oil treatment to remove remaining hair colour while restoring moisture to your hair. Warm the oil in the microwave according to package directions then apply it to your hair. Wrap your hair in a clean towel and allow the oil treatment to remain on your hair for 20 to 30 minutes.
Shampoo and rinse your hair again to remove the hot oil treatment and remaining hair colour.
Do a strand test on your hair before applying permanent colour so you can see if you will like the results or not. For best results, change your hair colour by only one to two shades when colouring at home. Drastic hair-colour changes require more steps and processing than is usually accommodated by a home hair-colouring kit.
Horrible hair-colour disasters are best handled by professional stylists.
