What directly affects nail flexibility?

• A. Thickness of the nail bed
• B. Water content
• C. Type of polish used
• D. Your diet

Answer: (B)

The direct connection between nail flexibility and water content is rooted in the composition of the nails themselves, which are primarily made of a protein called keratin. Nails with an optimal amount of moisture tend to be more flexible and less prone to brittleness and breaking. When the water content in the nails is high, it allows for elasticity, providing the nails with the ability to bend without breaking.

In contrast, lower water content can lead to dry and brittle nails, making them more likely to snap or chip. This is why maintaining proper hydration, both internally through adequate fluid intake and externally by using moisturizing products, is crucial for healthy and flexible nails. Other factors, while relevant to nail health, do not have as direct an impact on flexibility as water content does.
