What term describes the hardening of the cells in the nail plate?

The hardening of the cells in the nail plate is known as keratinization. This process involves the production of keratin, a protein that contributes significantly to the structure and strength of the nails. During keratinization, cells in the nail matrix produce keratin and undergo a transformation that results in the cells becoming hard and dense, ultimately forming the hard surface of the nail plate.

Keratinization is essential for maintaining the integrity and durability of nails, as this hardened structure protects the underlying tissues. Understanding the role of keratin and the process of keratinization is crucial for professionals in beauty therapy, especially when providing manicures and pedicures, as it affects nail health and aesthetics.
