How does lower water content affect the nails?

Lower water content in the nails leads to a decrease in their flexibility. This is due to the structural composition of keratin, the protein that makes up nails. Keratin holds moisture, which is essential for maintaining the elasticity and flexibility of the nail. When the water content is reduced, the nails become more brittle and prone to cracking or breaking, as they lose their ability to bend without breaking. With less moisture, the molecular structure of keratin becomes less pliable, resulting in stiffer nails that do not have the ability to adapt to stress as effectively. In summary, lower water content compromises the nails' flexibility, making them more rigid and susceptible to damage.
