In the context of resistant porosity, the cuticles are characterized as being smooth. This smoothness is indicative of healthy hair that has a well-functioning outer layer, which helps in maintaining moisture within the hair shaft and provides a protective barrier. When the cuticle layers lie flat against the hair shaft, it reduces frizz, tangling, and other issues associated with high porosity hair, where the cuticles may be lifted or damaged.

Smooth cuticles imply that the hair can effectively retain color and moisture, leading to a more vibrant and healthier appearance. This understanding of cuticle condition is critical in hairstyling and treatment, as it impacts how hair responds to various products and treatments. Knowing the state of the cuticles allows stylists to tailor their approaches to each client's specific hair needs.
