Help me find this hair color!

If your hair has natural red undretones you do not have to add much if any red to a color to get it that red. When you lift color with a golden blond the red undertones will come through. If you want to add some red to make sure they do than get two colors. If you are a medium brown say level 6 than go with a 7 or 8 level golden blond (add some strawbery if you want but be careful you might come out real red unless you don't have red undertone which would be very unusual). If you wanted less red or to try to go back you would need an ash even a neutral with red undertones wouldn't do it.
