What is the purpose of sponge rods in the chemical texturizing process?

Sponge rods are used in the chemical texturizing process primarily because they are pliable foam rods that allow for the shaping and texturizing of hair during chemical treatments. Their softness and flexibility make them ideal for creating various wave patterns or curls in the hair, which is essential when performing processes like perming or setting textures. As the chemical solution interacts with the hair while it is wrapped around these rods, it facilitates a permanent alteration in the hair’s structure, resulting in the desired level of wave or curl. This ability to conform to different hair lengths and types allows stylists to achieve a range of styles and ensures that the chemical texture applied is uniform throughout the hair.
