In this fourth instalment of our series on the key properties of natural and artificial nails, we’ll focus on nail toughness. We’ve already discussed strength, hardness, and flexibility—each of these properties plays an essential role, but toughness is the combination of both strength and flexibility in balance. This perfect blend creates nails that are durable, resilient, and resistant to damage in everyday situations. Toughness is what we really want for our nails, ensuring they are both strong enough to withstand pressure and flexible enough to bend without breaking.
What Is Nail Toughness and Why Do Nails Need It?
Toughness is defined as the ability of a material to absorb energy and deform without breaking, making it a balanced combination of strength and flexibility. Nails, whether natural or artificial, need to be tough to protect the delicate tips of our fingers and toes. The more balanced the nails are between strength and flexibility, the tougher they will be.
An excellent example of toughness can be found in nylon fishing lines. Although about the same thickness as cotton string, nylon is much more resistant to breakage due to its perfect balance of strength and flexibility. Similarly, the plastic rings used to hold soda cans together are incredibly tough, able to stretch without snapping. The same principle applies to both healthy hair and nail plates—they are tough materials because they balance strength and flexibility.
The Relationship Between Nail Hardness and Toughness
Nail toughness is closely related to hardness, another key property we’ve already explored. While hardness refers to a nail’s resistance to surface damage like scratching, toughness ensures that the nail can bend and absorb impact without cracking or breaking. Nails that are too hard without sufficient flexibility will become brittle, leading to breakage. On the other hand, nails that are too soft and flexible may not have the necessary durability to resist daily wear and tear.
In both natural and artificial nails, the balance of these properties is crucial. When nails are too rigid or too soft, toughness is lost, and the nails become more susceptible to damage. This is why products and treatments need to be tailored to ensure the nails have enough strength and flexibility to remain tough.
Why Toughness Matters for Both Natural and Artificial Nails
Toughness is one of the most important properties for nail plates, as they must endure the stresses of daily activities such as typing, gripping, and exposure to environmental factors. Without toughness, nails can become brittle, prone to splitting or cracking. For artificial nails, ensuring that the coatings provide enough toughness is essential for preventing service breakdowns and flexibility helps to prevent peeling or lifting.
When nails lose toughness, it is often because the balance between strength and flexibility has shifted. Too much strength without enough flexibility can make the nails brittle, while too much flexibility without enough strength can make them weak. The result is a loss of durability and increased susceptibility to damage. This delicate balance is why nail care professionals must be mindful of the treatments and products they use, ensuring that toughness is maintained.
Enhancing Nail Toughness for Optimal Health
The key to enhancing nail toughness is maintaining the right balance between strength and flexibility. For natural nails, this means proper nail care routines that include moisturizing, protecting the nails from excessive water exposure, and avoiding harsh chemicals that can dry out and weaken the nail plate. For artificial nails, it involves choosing the right systems, such as those that balance flexibility and strength, ensuring that the nails can withstand the stress of daily life.
In conclusion, toughness is a vital property of nails, combining both strength and flexibility to create durable and resilient nail plates. By understanding and enhancing toughness, you can help ensure that your nails—whether natural or artificial—are equipped to handle the demands of everyday use.
