Where is the cortex located in the hair structure?

1. Outermost layer

2. Directly beneath the cuticle layer

3. Innermost layer

4. Above the medulla

The correct answer is: Directly beneath the cuticle layer

The cortex is located directly beneath the cuticle layer. This is because the cortex is responsible for providing strength, elasticity, and color to the hair shaft. If the cortex were located on the outermost layer (A) or innermost layer (C), it would not have as much protection or support from the cuticle layer, leading to potential damage and breakage. The cortex is also located above the medulla (D), which is the innermost layer of the hair shaft but does not play as significant of a role in the overall hair structure as the cortex does.
