What is the outer covering of the hair strand made up of overlapping layers of transparent scales called?

• A. Cortex
• B. Cuticle
• C. Papilla
• D. Medulla

Answer: (B)

The outer covering of the hair strand, consisting of overlapping layers of transparent scales, is known as the cuticle. This structural component serves as a protective barrier for the inner layers of the hair, which include the cortex and medulla. The cuticle's overlapping nature helps to prevent moisture loss and damage from environmental factors. Each scale-like layer allows the hair to appear smooth and shiny while contributing to its overall strength and resilience. Understanding the anatomy of hair is essential, especially in hair removal and care practices, as the condition of the cuticle can significantly influence how hair responds to different treatments or products. This knowledge can help in determining the most appropriate methods for hair removal and maintenance in various situations.
