What step is performed prior to applying a single-process color on virgin hair?

1. Parting dry hair

2. Applying a deep conditioner

3. Wetting the hair

4. Brushing the hair

The correct answer is: Parting dry hair

Prior to applying a single-process color on virgin hair, parting the dry hair is an essential step. This preparation allows for systematic application and ensures that the color is evenly distributed throughout the hair. Proper parting helps the stylist to avoid missing any sections and guarantees comprehensive coverage, which is particularly important for achieving a uniform color result on virgin hair that has not been previously treated. While other actions, such as applying a deep conditioner or brushing the hair, can be part of the general hair preparation process, they do not specifically pertain to setting up for a color application like parting does. Wetting the hair is also not advisable before applying single-process color, as this can dilute the color and affect the final result. Therefore, parting dry hair is the most crucial and appropriate step to take before proceeding with the coloring process.
