What length of hair is the spiral technique most often used on?

• A. Short
• B. Medium to long
• C. Very long
• D. Extra short

Answer: (B)

The spiral technique relies on wrapping hair around perm rods in a continuous spiral to create long, flowing curls with good movement. To get that elongated, smooth spiral, there must be enough length to wrap around the rod and extend into the spiral. Short hair can’t form a defined spiral and tends to yield tighter, less natural curls. Extra short is impractical for spirals. Very long hair can be wrapped, but it can be heavy and harder to control, risking uneven results. Medium to long hair provides the right balance: enough length to form a clean, elongated spiral with consistent curl and easier processing.
