What procedure is used to remove excess waving lotion during the perm process?

Rinsing is the procedure used to remove excess waving lotion during the perm process because it effectively washes away any remaining chemicals from the hair. After the waving lotion has been applied and allowed to process, it is essential to remove the product to halt its action and prevent potential damage to the hair. Rinsing ensures that the hair is cleansed of these chemicals, allowing for the next steps in the perming process to proceed without interference from the waving lotion.

While applying refers to the initial step of putting the waving lotion on the hair, and setting involves arranging the hair into the desired curl pattern, these actions do not address the need to eliminate excess product. Conditioning, on the other hand, is typically performed after rinsing to help restore moisture and manageability to the hair, but it does not directly remove the waving lotion. Therefore, rinsing is the most critical technique at this stage to ensure the perming process is successful and the hair health is maintained.
