What is a proper approach to applying color during a service?

• A. Apply color from the ends toward the roots.
• B. Apply color only to the roots.
• C. Apply color from root to ends in a systematic way.
• D. Apply color to the scalp and hair at once.

Answer: (C)

Applying color from the roots to the ends in a systematic way ensures even saturation and predictable processing. By starting at the scalp, you place color where it will develop first and then move outward so each section processes together, reducing the chance of patchiness or a visible line of demarcation. Sectioning hair into manageable subsections and applying evenly keeps every strand exposed to a consistent amount of dye, which helps the overall tone stay uniform. If you go ends-to-roots, the ends are often more porous and can over-develop before the roots catch up, leading to uneven results. Coloring only the roots leaves the mid-lengths and ends mismatched, and applying to scalp and hair at once can cause irritation and uneven saturation. So root-to-end in a systematic pattern gives the most reliable, uniform outcome.
