Go All Gray
Q: I have short gray hair that I've been dyeing for years. I hate it when it starts to grow out and I need to re-dye. I want to just go all gray at once.Can I use Colorfix to remove the color from my hair, so I will be gray? What is the best way to go back to my natural gray? Thanks.
A: I’ve done some research and after reading scores of reviews on the product in question, I can find nothing to indicate that it will return you to your “natural” gray hair color.
What I would recommend, is that you use the product (as directed, possibly leaving out the processing step as reports indicate that it tends to be very harsh on the hair and causes a re-darkening) to lighten the color. After that, I would suggest aiming for a pale blonde color that is in the cool range (with a blue base color).
I know that this won't get you your true gray hair, but it will give you a hair color that will be an easier transitional color as your gray hair grows out. I don't know of anything that will give you your natural gray color, however, you can reach a color that is less contrasting, which will allow for a subtler transition.
