The required method for applying hair color is typically on towel-dried hair. This technique allows for better absorption of the color and helps achieve a more even application. When hair is damp, the cuticle layer is slightly raised, which allows the color molecules to penetrate the hair shaft more effectively than on completely dry hair. This method can also minimize damage caused to the hair, as overly dry hair may not retain moisture well during the coloring process.

Applying hair color directly on dry hair may lead to uneven results, as dry hair can resist absorption. Similarly, applying color on fully damp hair could dilute the color or affect its vibrancy, depending on the specific product being used. Saying that any method will work ignores the nuances of hair texture and the chemistry of the color products, which can impact the final outcome significantly. Thus, for optimal results, towel-dried hair is usually the best foundation for applying hair color.
