In a diagram of non-porous hair, the scales of the cuticle layer appear reflected. This is characteristic of non-porous hair, which typically has a smooth cuticle layer. The reflected appearance of the cuticle scales indicates that they are tightly packed and lie flat against the hair shaft. This structure helps to create a barrier that minimizes moisture loss and enhances the hair’s shine and overall health.

Given the conditions of non-porous hair, the reflected scales play a crucial role in preventing damage from external factors. Understanding this visual representation is fundamental for identifying hair types and determining suitable hair care treatments.
