A cosmetologist arranges perm rods and base sections in curved rows that follow the shape of the head to create a directional curl pattern that flows with the client's finished design. Which wrapping pattern is this?

  1. ACurvature wrap
  2. BBricklay wrap
  3. CWeave technique
  4. DPiggyback wrap
Show answer & explanation

Correct answer: A. Curvature wrap

A curvature wrap uses curved base sections and rod placement that follow the head's contours, allowing curl movement to flow in a specific directional pattern for the finished style.

Why the other options are wrong

  • B. Bricklay offsets bases to avoid straight-line partings but does not create directional curved rows.
  • C. Weave technique perms alternating strands within a section, not curved base rows.
  • D. Piggyback wrapping stacks two rods on one long strand, unrelated to directional curve design.
