Iowa Cosmetology Practice Exam

How can you tell if a perm has processed correctly?

1. The hair should have a sharp, defined curl

2. The hair should have a soft, uniform wave

3. The hair should be completely straight

4. The hair should feel greasy

The correct answer is: The hair should have a soft, uniform wave

Determining if a perm has processed correctly involves evaluating the texture and shape of the curls or waves in the hair. Soft, uniform waves indicate that the perm solution has worked effectively to change the hair's structure while maintaining a natural look and feel. This outcome suggests that the chemicals have penetrated the hair properly, altering the bonds and creating a lasting wave. A sharp, defined curl could be a sign of over-processing, which can lead to damage or an unnatural appearance. Completely straight hair indicates that the perm did not take, showing that the solution did not sufficiently alter the hair's structure. Feeling greasy may suggest the presence of excess perm solution or inadequate rinsing, neither of which reflects a successful perming process. Overall, a soft, uniform wave is the hallmark of a successful perm, demonstrating the method's intended outcome.
