What type of hair texture has an average of seven to ten cuticle layers and accepts products well?

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

Answer: (C)

Understanding hair texture and cuticle layers helps explain how hair behaves in chemical services. The cuticle is the outer protective shield, and its density varies with texture. Medium texture sits between fine and coarse, typically with about seven to ten cuticle layers. That range provides a balanced barrier: it’s not so tight that products struggle to penetrate, and not so loose that the hair swells or overdamps quickly. With this middle-ground structure, medium-textured hair tends to accept processing products well, giving reliable, even results. Fine hair, with fewer layers, can be more delicate and over-responsive or over-porous, while coarse hair, with more layers, is more resistant to product penetration and can require longer processing. Very coarse hair would be even more resistant.
