Define on-base, half-off-base, and off-base wrap positions and how they influence base control and curl.

• A. On-base keeps the rod over the base area for maximum base control and lift; half-off-base provides medium control and lift; off-base places the rod away from the base for the least base influence.
• B. On-base places the rod away from the base area for maximum base control.
• C. Half-off-base places the rod directly on the base for maximum lift.
• D. Off-base positions give the most base control.

Answer: (D)

Wrap position relative to the base determines how much the root area is held by the rod and thus how much curl and lift you’ll get. On-base means the rod sits directly on its base against the scalp, giving the hair at the root strong support from the rod. That produces maximum base control and a tighter curl with more lift from the scalp. Half-off-base places the rod halfway off the base, reducing the base’s hold, which yields medium base control and a gentler curl. Off-base moves the rod away from the base, minimizing the base’s influence on the root and resulting in the loosest curl with the least base control. In short, the closer the rod is to the base, the stronger the base control and curl; the farther away, the weaker the base control and curl.
