Which component of a curl determines the amount of movement?

• A. ARC
• B. Diameter
• C. Base
• D. Texture

Answer: (A)

Movement in a curl comes from the arc of the curl—the portion of the circle the hair follows as it wraps around the tool. A larger arc makes the hair travel through a wider part of the circle, giving a more open, expressive curl with more movement. A smaller arc keeps the curl tighter and closer to the scalp, resulting in less movement. The other factors set different aspects: diameter affects curl size and pattern, base relates to where the hair sits on the tool, and texture influences grip and hold. But the arc is the part that directly determines how much the curl moves.
