Resistant porosity means that the cuticles are

• A. Smooth
• B. Rough
• C. Damaged
• D. Porous

Answer: (A)

Resistant porosity means the cuticle scales lie flat and tightly closed, creating a smooth surface. When the cuticles are smooth, they form a strong barrier that resists moisture and chemical penetration, so the hair doesn’t absorb easily. That’s why smooth cuticles best describe resistant porosity. If the cuticles were rough or damaged, they’d lift or have gaps, leading to higher porosity and easier absorption, which isn’t what resistant porosity signifies. Porous would imply many open gaps, not a smooth, tightly bound surface.
