Explanation:
- The cortex is the main body of the hair shaft - it contains natural moisture and color pigment, which is the translucent cuticle.
- The outer layer of the hair shaft, its cuticle, must be opened before permanent color can be deposited into the hair. Once the cuticle is open, the dye reacts with the inner portion of the hair, the cortex, to deposit or remove the color.
