Which shape is used to move the hair in equal proportions from a center point of origin?

• A. Half-circle
• B. Circle
• C. Triangle
• D. Square

Answer: (A)

Moving hair in equal proportions from a central point uses a semicircular path because the arc gives a smooth, continuous spread around the origin, ensuring each radial section carries the same amount of hair. This symmetry helps create balanced weight and even distribution when shaping from that center. A full circle would complicate the pattern and can lead to overlapping or uneven results around the head, while a triangle or square imposes corners and unequal section sizes, producing uneven weight. The semicircle is the practical shape for radiating hair evenly from a center point.
