What could cause uneven color results?

• A. Incorrect Mixing Ratio
• B. Improper Lighting
• C. Poor Application or Uneven Porosity
• D. Too Much Heat

Answer: (C)

Uneven color results happen when pigment doesn’t deposit uniformly on the hair. The most common cause is varying porosity along the hair strand or across the scalp. Porosity is how readily hair can accept pigment; some areas are more porous and soak up more color and process faster, while others are less porous and take up less color. That difference in uptake creates patchy or streaky results. If the color isn’t applied evenly—sections loaded with product inconsistently, gaps in coverage, or brush strokes not being smoothed—the pigment won’t distribute uniformly, reinforcing the uneven appearance. Other factors can affect the final look, but they aren’t the primary source of patchiness: incorrect mixing ratio tends to shift tone or processing time globally rather than create patches; lighting can alter how we perceive color, and excessive heat can change processing speed, potentially affecting results if uneven, but the core issue for uneven color is inconsistent deposition from porosity differences and application.
