    protein forming hair, nails, and skin's outer layer

    Keratin is a type of protein that forms the structural foundation of hair, nails, and the outer layer of skin. It provides strength and protection, making these tissues resilient and less prone to damage. In hair, keratins are essential for maintaining its integrity and elasticity, and they play a crucial role in the hair's overall health and appearance.
