Zonal perms are also commonly referred to as what type of perms?

Zonal perms are known as partial perms because they involve styling specific sections or zones of the hair rather than treating the entire head. This technique allows for focused volume or curl enhancement in selected areas while leaving other parts of the hair straight or with a different texture. This approach is particularly useful for clients who want to add body, texture, or curls to specific areas without committing to a full perm, which would alter the entire hairstyle.

Understanding zonal or partial perms is crucial for hairstylists as it provides versatility in styling and caters to individual client preferences, enabling a more customized hair solution.
