If a client has no contraindications, what is the primary factor to assess before a chemical texture service?

• A. Aftercare preference
• B. Hair color
• C. Elasticity
• D. Mood

Answer: (C)

Elasticity of the hair is the key factor because it shows how well the cortex and bonds can handle the chemical swelling and tension during processing. If the hair can stretch a bit and rebound, it indicates enough strength to withstand the chemicals; if it breaks or doesn’t return to shape, there’s a higher risk of damage. A quick strand test—gentle stretch of a clean strand—helps you gauge this: normal hair will elongate and recover, while damaged or low-elasticity hair will snap or stay stretched. When elasticity is good, you can proceed with standard processing guidelines. If elasticity is poor, you’d adjust the service—such as using milder product strength, shortening processing time, or postponing the service—to protect the hair. Aftercare, color decisions, or the client’s mood don’t reveal how the hair will respond to chemical texture processing, so they aren’t the primary factor to assess beforehand.
