<h4 class="dechead">On One Hand: Blondes Turn Green
If an ash color is used on naturally blonde hair or blonde-colored hair, it will most certainly turn green. An ash color, even if it is a shade of brown, usually has a green base. Blonde hair does not have any pigment, therefore it accepts all of the green into the hair instead of brown. A red-based color would have to be applied to the hair first in order to avoid having green hair. Green and red are complimentary and will neutralize each other.
On the Other: Red Hair Turns Brown
A redhead who does not wish to be red will benefit from using an ash color. Green and red are complimentary colors and they neutralize each other. A green-based color will correct unwanted red tones, without the fear of the hair turning green. The two colors together will make the hair brown.
Bottom Line
It is wise to leave the coloring to the experts. There are many considerations that play a part in choosing the correct hair color. Stylist rarely use one color in a formula. The color formula is determined by your natural hair level (at the roots), your existing color, your desired color and the condition of your hair.
