Why is proper shampooing before perming important?

Proper shampooing before perming is crucial because it removes buildup and ensures even distribution of the perm solution throughout the hair. Buildup from products like gels, sprays, and oils can inhibit the perm solution from penetrating the hair shaft effectively. If the hair is not clean, the chemicals used in the perm might not interact uniformly with the hair structure, leading to inconsistent waves or curls, and potentially damaging results.

By shampooing adequately, you are preparing the hair to absorb the perm solution evenly, which is essential for achieving the desired texture and style. This step is fundamental not just for the effectiveness of the perm but also for the health of the hair itself, as a clean base can minimize the risk of unexpected reactions with the perming chemicals. In contrast, adding fragrance, hydrating the hair, or aiming for shininess are secondary benefits and not the primary reasons for shampooing prior to perming.
