How should color-treated hair influence a chemical texture service plan?

• A. Color-treated hair may be more porous and weaker; adjust processing time and strength; perform strand tests; consider postponing if hair shows damage.
• B. Postpone regardless of hair condition and proceed with the strongest available chemical.
• C. Use the same processing time and strength as untreated hair.
• D. Ignore porosity and proceed with standard timing.

Answer: (C)

Color-treated hair often becomes more porous and weaker because color processing opens the cuticle and can disrupt internal bonds. That means it may react differently to chemical textures than virgin hair. The right approach is to treat color-treated hair with caution: start with strand tests to see how the treated strand responds, then adjust the processing time and the chemical strength based on those results. If the strand test shows rapid processing, signs of damage, or excessive swelling, you should shorten the time, use a milder strength, or even postpone the service until the hair is healthier. Using the same processing time and strength as untreated hair ignores these changes and increases the risk of overprocessing, breakage, and an uneven result. Porosity and condition matter here, so tailoring the plan to the hair’s current state is essential.
