Which hair texture may be resistant due to the increased number of cuticle layers?

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

Answer: (B)

Hair texture influences how easily chemical services penetrate the hair. When there are more cuticle layers, the outer barrier is thicker, making it harder for processing solutions to reach the cortex. Coarse hair typically has more cuticle layers than fine or medium hair, so it tends to be more resistant to chemical processing. Fine hair has fewer layers and processes more readily, while very coarse hair would be even more resistant, but in this context the texture described by increased cuticle layering is most closely associated with coarse hair.
