Which combination results in no curl at the scalp and minimal volume?

• A. On base with alkaline perm
• B. On base
• C. Off base
• D. Partial perms

Answer: (A)

The main idea is how base placement and the chemical used affect where curl forms and how much root volume appears. Wrapping on the base means the hair is laid flat against the scalp with the tool held right at the scalp, and using an alkaline perm makes the solution more aggressive in breaking bonds and causing the hair to swell. When the rod sits directly on the base and the hair swells, the root area can flatten against the scalp, so little or no curl develops right at the scalp and the roots stay relatively flat, which translates to minimal volume at the roots. The curl pattern tends to show up further down the strand rather than at the scalp, leading to the appearance of no curl at the scalp with minimal root lift.

In other cases, changing the base position or using a different type of perm would shift where the curl forms and how much volume sits at the roots, which is why those options wouldn’t align with having no curl at the scalp and minimal root volume.
