Hair is broken down into 3 components
- The Cuticle …often described like fish scales or roofing tiles for a visual comparison. This is the layer that protects the hair.
- The Cortex …responsible for the hairâ€™s elasticity, flexibility, strength, and colour. It is inside this area that permanent colour forms acid bonds with keratin chains and becomes part of the hair structure.
- The Medulla …this innermost section of the hair has an unknown function. Itâ€™s not unusual to find healthy, normal hair without a medulla!
