What is the term for using an ingredient other than ammonia to reduce odor in hair perms?

The term for using an ingredient other than ammonia to reduce odor in hair perms is known as ammonia-free waves. These formulations typically utilize alternative alkalizing agents that do not produce the strong, unpleasant smell usually associated with ammonia-based perms. This makes the perming process more pleasant for both the client and the stylist, as it significantly reduces the odor during the application.

In addition to enhancing the overall experience, ammonia-free waves can also be gentle on the hair compared to traditional perm solutions, providing a milder alternative that can help to minimize damage. Therefore, when seeking options that are less offensive in terms of smell and potential hair damage, ammonia-free waves emerge as a favorable choice in the realm of hair chemical treatments.
