What does the term "curl retention" refer to?

Curl retention refers to the ability of hair to maintain its curl pattern after the perming process has been completed. This concept is central to understanding how chemically altered hair can hold the desired curls over time. Proper curl retention is influenced by various factors, including the hair’s natural texture, the type of perm solution used, and the technique applied during the perming process.

In essence, when a perm is successful, the curls formed should remain intact and resilient against humidity, washing, and styling. This quality is crucial for clients seeking long-lasting, beautifully defined curls from their perm treatment, making curl retention a key measure of effectiveness for any perm service.
