When hair becomes an unwanted tone such as red or orange, ash colors can be used to help neutralize or cut down these tones. For instance, if your hair is red, a green-based hair coloring product will counter-act the red tones in your hair. Ash-base colors are great for neutralizing brassy tones. But if you use a green-based ash hair color on yellow-blonde hair, it will result in a green cast. It's best to follow the instructions carefully when using any ash-base colors. |
