A cosmetologist is wrapping a client's hair for a perm and positions each strand so it is wound directly on top of its base section, with the rod sitting squarely on the panel. What effect does this on-base placement have on the resulting curl?
- AIt has no effect on volume, only on curl direction
- BIt produces minimal volume with curl formation beginning far from the scalp
- CIt causes the curl to fall below the base, creating a flat, close-to-head result
- DIt produces maximum volume and curl close to the scalp
Show answer & explanationAnswer & explanation
Correct answer: D. It produces maximum volume and curl close to the scalp
On-base placement (wrapping the strand directly over its base section with the rod sitting on the base) produces maximum volume and lift because the curl forms as close to the scalp as possible; this contrasts with off-base wrapping, which reduces volume by positioning the curl further from the scalp.
Why the other options are wrong
- A. Base placement significantly affects volume, not just direction.
- B. Minimal volume with curl far from scalp describes off-base or under-directed wrapping, not on-base.
- C. Flat, close-to-head results describe off-base placement, the opposite effect.
On-Base Placement
A wrapping technique where the strand is wound with the rod sitting directly on top of its base section, producing maximum volume and curl close to the scalp.
- Rod sits squarely on the base section
- Produces maximum volume/lift
- Contrasts with off-base (reduced volume) placement
Memory trick: On-base sits right on top of the mountain—maximum lift, closest to the peak (scalp).
