Which base direction requires a base of at least 1 1/2X and positions the rod in the lower half, resulting in moderate base lift and is used in the perimeter?

Which base direction requires a base of at least 1 1/2X and positions the rod in the lower half, resulting in moderate base lift and is used in the perimeter?

• A. Half-off base
• B. On-base
• C. Underdirected
• D. Overdirected

Answer: (C)

In perm theory, how you position the base and direct the wrap determines how much lift you get and where the curl sits, especially along the perimeter. If you want a moderate lift with a softened edge at the hairline, you use a base that's at least 1.5 times the rod and place the rod in the lower half of that base. This setup tilts the curl less aggressively than a full-on on-base wrap, so the lift stays controlled. That specific approach matches an underdirected base direction—directing the wrap less than the natural direction to produce a gentler curl around the perimeter. The other options wouldn’t fit this combination: on-base would give stronger lift; half-off base changes lift but doesn’t emphasize the larger base and lower-half placement; overdirected would create more lift than desired; undirected would follow the natural direction without the lower-half positioning described.
