Step-by-step explanation:
One factor that could complicate color procedures for clients with long hair is the amount of hair dye needed. Clients with long hair typically have more hair follicles, which means more dye is required to cover all the hair evenly. This can make the coloring process more time-consuming and costly. Additionally, applying dye to long hair can be more challenging as it requires careful and precise application to ensure even coverage.
