Avoid Redness in Brown Hair
Q: I have medium to dark brown hair. Every time I try to dye it to its natural color, it turns red. How do I get the red out? What kind of dye do I need to get? I just want brown not red in it.
A: The problem is one of conflicting base tones in the coloring process. From your description, your hair naturally has a reddish base color tone and the color you are using to dye your hair is most likely one with a base of red as well. When the two factors combine, you get the reddish result that you are not happy with.
In the same vein, when your hair has a natural pigment base of a reddish tone, and you add haircolor that has a base color of red, you end up with an intensification of the red shade in the resultant color.
To neutralize the redness, you should go to your beauty supply store and look for a hair color formula in the shade you want with a base color that is listed as “green” or “drab”. (Drab became used as a color name instead of green because of the concern many women showed that their hair would turn green using the color. That prejudice has been largely removed, so that some manufacturers have returned “green” to the label.)
Using the green-based color should neutralize the overabundance of red in the resulting color and give a more natural-looking brown tone.
