What is the first step in planning a color correction service?

• A. Assess starting color and undertone
• B. Choose final shade without testing
• C. Skip strand tests
• D. Use the strongest developer initially

Answer: (A)

Assessing the starting color and undertone is the essential first step because it reveals exactly what needs to be corrected and how it will behave when you lift and deposit color. By identifying the current level and the underlying pigments, you can determine the neutralization strategy for any brassiness or unwanted warm tones and choose a target shade that will sit at the right level with the correct tone once finished. This information also guides the formulation choices, including the appropriate developer strength, processing time, and whether you’ll need to stage the correction. Getting this right helps you predict the result and protect the hair from over-processing by avoiding assumptions about the final look.

Skipping this assessment and jumping straight to picking a final shade invites surprises, because undertones may not match the desired outcome, leading to a mismatched result. Similarly, relying on the strongest developer upfront risks overly lifting or damaging the hair without guaranteeing the intended tone. After the initial assessment, strand tests and gradual checks help verify the plan as the hair responds.
