When hair color is applied, the final result is based on the existing/contributing pigment and what?

• A. The natural pigment
• B. Underlying pigment
• C. The base pigment applied
• D. Artificial pigment applied

Answer: (D)

The final shade comes from the combination of the hair’s current contributing pigment and the pigment added by the color product. The existing pigment sets the baseline tone and undertone, while the artificial pigment deposited by the dye provides the new color. Together, they determine the result—how warm or cool, light or dark the hair ends up. This is why choosing a dye with the right artificial pigment is crucial: it interacts with what’s already there to produce the final result you see.
