Keratin

Real World Example

Imagine trying to protect your phone during a rainstorm without a proper case. Just as a waterproof case shields your phone from water damage and keeps it functional, keratin acts as a protective barrier in our bodies. Keratin is like the phone case for our hair, nails, and skin, providing a hard, waterproof shield that maintains their structure and prevents damage from everyday wear, much like the case protects your phone from the elements.
