Final answer:
Using a base section that is wider than the perm rod can create an uneven curl pattern and undue tension on the hair.
Step-by-step explanation:
A. True
Using a base section that is wider than the perm rod can indeed create an uneven curl pattern and undue tension on the hair.
For example, if the base section is too wide, the hair can slip out of the perm rod, resulting in loose and inconsistent curls. On the other hand, if the base section is too narrow, the hair can become excessively tight and may lead to breakage or damage.
