Which hair texture may be more resistant due to the finely packed cuticle?

• A. Fine hair
• B. Coarse hair
• C. Medium hair
• D. Very fine hair

Answer: (A)

Understanding how the cuticle packing affects porosity and chemical penetration is key. When the cuticle scales lie flat and are tightly packed, the barrier is stronger, reducing porosity and making hair more resistant to chemical processing. Fine hair often has a cuticle that sits more densely packed, so it tends to resist chemical penetration more than coarser textures. Coarse hair has looser, more lifted cuticles, which increases porosity and lowers resistance. Medium hair falls in between. While very fine hair shares the small diameter, the scenario here points to the finer cuticle arrangement seen in fine hair as the cause of greater resistance.
