What term describes the ridge separating activated textures from unactivated textures in graduated texture?

• A. Form line
• B. Ridge line
• C. Inclination
• D. Perimeter line

Answer: (B)

In a graduated texture, you’re creating a transition from worked, textured areas to smoother, untextured areas. The line where those two texture states meet forms a visible boundary in the hairstyle. That boundary is the ridge line. It marks where activated texture ends and unactivated texture begins, guiding how weight sits and how the hair will fall as the cut graduates from shorter, lifted sections to longer, flatter ones. The other terms describe different ideas: form line is about the overall silhouette, inclination refers to the cutting angle, and perimeter line is about the outer edge of the shape.
