A client wants a drastic color change but hair has been previously colored with multiple tones. What is the proper initial approach?

• A. Start with the target color immediately.
• B. Only perform strand tests and proceed if they pass.
• C. Assess existing levels and undertones; plan controlled lift with fillers; perform strand tests; present the plan.
• D. Recommend a gloss or glaze and delay color change.

Answer: (C)

Understanding how to approach a drastic color change on hair that’s already multi-toned starts with evaluating the current levels and undertones, then planning a controlled lift with fillers. Knowing the existing levels and underlying hues guides how you lift and balance porosity across the strands, which helps create a smooth, even canvas for the new shade. Using fillers during this lift is key because they rebalance the color molecules and porosity differences, reducing the chance of patchy or brassy results. After that plan is set, perform strand tests to verify how the hair responds and to fine-tune the approach before presenting a clear, approved plan to the client. Jumping straight to the target color ignores the actual starting points and can lead to unpredictable results, while relying only on strand tests or delaying with a gloss won’t address the necessary steps to achieve a consistent, salon-perfect outcome.
