Eyebrow tinting is something that is done at a salon by a specialist. Eyebrow tinting is pretty much dying your eyebrow to match your hair color. You should never try this at home because the time to keep on tint is much short and dye has to be place just right or you will have dye makes above and below your eyebrows.
Matching the color of your eyebrows to the color of your hair is important. If you dye your hair, you should consider tinting your eyebrows so that both colors go together.
