What is applied prior to wrapping hair around rods during some perms?

Before wrapping hair around rods during some perms, pre-wrap solutions are applied to prepare the hair for the perming process. This solution helps to ensure that the hair is properly conditioned and protects it from potential damage caused by the chemicals used in the perm. Pre-wrap solutions can also aid in the absorption of the perming solution, allowing for a more uniform and effective curl formation.

Other products, while potentially useful in different contexts, do not serve the same preparatory function during the wrapping process. Setting lotion, for example, is typically used after perming to help maintain the shape and hold of the style. Hair gel, on the other hand, is more suited for providing hold and style for finished looks rather than preparing hair for chemical treatment. Curl activators are primarily designed to enhance curls in naturally curly hair rather than to assist in the perming process.
