How should color be applied to gray hair to achieve even coverage?

When applying color to gray hair, starting with the gray areas is essential for achieving even coverage. Gray hair often has different texture and porosity compared to pigmented hair, which means it may require more attention during the coloring process.

Gray strands can absorb color differently, and initiating the application on these areas allows the color to fully develop without compromising the saturation levels in the previously pigmented sections of the hair. By beginning with the gray, the stylist ensures that those strands receive the necessary exposure to the color for optimal coverage and vibrancy before moving on to the rest of the hair.

The techniques suggested by the other options, such as applying to the ends first or mixing the color with a conditioner, do not adequately address the unique characteristics of gray hair and could result in uneven color. Additionally, applying a lighter color all over may not provide the necessary coverage for gray strands specifically. Thus, starting the application on gray areas effectively improves the overall hair color outcome.
