How can previous color-treated hair influence chemical texture results?

• A. Coloring has no effect on chemical textures.
• B. Coloring can alter cuticle structure and porosity and affect chemical penetration; may lead to inconsistent results; may require adjustments in processing time or conditioning.
• C. Coloring always improves processing consistency.
• D. Coloring reverses the reformation pattern.

Answer: (B)

Color-treated hair changes how chemical textures behave because dyeing can damage or lift the cuticle and create uneven porosity. When the cuticle is raised or irregular, chemical solutions can penetrate more in some areas and less in others, leading to uneven processing of the cortex and unpredictable results. Pigment residues and residual color chemicals can also interfere with how the reducing agent breaks disulfide bonds and how the neutralizer reforms them, which can shift processing times and conditioning needs. Because of these variations, technicians often adjust processing time, use strand tests, and include conditioning or pre-treatment to balance porosity before texturizing. Statements claiming no effect, universal improvement, or reversal of bond reformation don’t fit the reality that color exposure changes the hair’s surface structure and how chemicals interact with it.
