Which of the following is NOT typically considered when selecting a relaxer type, strength, and processing time?

• A. Hair length
• B. Porosity
• C. Curl pattern
• D. Overall hair condition

Answer: (A)

The main idea is that choosing a relaxer type, strength, and how long to process is guided by how the hair will respond chemically, not by how long the hair is. Porosity tells you how easily moisture and chemicals can penetrate the cuticle, which affects processing time and whether a milder or stronger formula is appropriate. Curl pattern helps determine how much straightening you’re aiming for, guiding the strength and duration to achieve the desired result without over-processing. Overall hair condition shows how resilient the hair is to chemical treatment, influencing both product choice and timing to minimize damage. Hair length doesn’t change the chemical reaction happening in the cortex, so it isn’t a primary factor in deciding the relaxer type, strength, or processing time. You may adjust technique for even application on longer hair, but the decision about product and time is driven by porosity, curl pattern, and condition.
