Low porosity hair typically requires which processing adjustment?

• A. Shorter processing times and less conditioning
• B. Longer processing times and heat to open cuticle
• C. No processing changes
• D. Immediate results with no conditioning

Answer: (A)

Low porosity hair has a cuticle that lies very flat, making it harder for moisture and chemicals to penetrate. Because the hair surface can glaze over with product or conditioner, there's a greater risk of uneven uptake or surface buildup if processing is allowed to sit too long or if heavy conditioning is used beforehand. By keeping processing times shorter and using less conditioning before applying the chemical treatment, you minimize the barrier on the outside of the hair and reduce the chances of overprocessing or uneven results. This approach helps the treatment work more consistently with hair that resists penetration. After the processing step, conditioning can be used to restore moisture and smoothness.
