What Perm Pattern is also known as 9-block?

What Perm Pattern is also known as 9-block?

• A. Rectangle pattern
• B. Diagonal grid
• C. Circular pattern
• D. Diamond pattern

Answer: (A)

The main idea here is how perm patterns describe the arrangement of perm rods on the scalp. A 9-block setup means three blocks across by three blocks down, forming a neat, gridlike pattern. That aligns with the rectangle pattern, since the blocks line up in straight rows and columns to create a rectangular grid. The other patterns describe different alignments—diagonal grid twists the rows into a slanted layout, circular pattern arranges blocks in a circle, and diamond pattern uses a rotated square grid. So the 9-block configuration matches the rectangle pattern most closely, giving a uniform grid of curls.
