Medium hair is defined by having how many cuticle layers on average?

• A. Three to five
• B. Seven to ten
• C. Eleven to fifteen
• D. Sixteen to twenty

Answer: (B)

Hair cuticle layers are the outer protective covering of the hair shaft, made of overlapping scale-like cells. The number of these layers varies with hair texture: finer hair has fewer layers, while coarser hair has more. In common classifications, fine hair typically has about 3–5 layers, medium hair about 7–10, and coarse hair about 12–20. The seven-to-ten range for medium hair reflects a balance—enough layers to provide protection and strength, but not so many that the hair feels thick or rigid. This helps explain how medium-textured hair behaves with products and chemical services. Therefore, seven to ten layers best describe medium hair.
