Why should nail technicians avoid using metal tools on clients' natural nails?

Using metal tools on clients' natural nails is discouraged primarily because they can damage the natural nail surface. Metal implements, such as metal files or pushers, can be abrasive and may inadvertently create microscopic tears or weaken the nail structure, leading to splits and breaks. Natural nails have a delicate keratin layer that can be compromised when subjected to harsh tools.

In manicure and pedicure practices, it is essential to maintain the integrity and health of the natural nails. This is why softer tools, such as those made from plastic or glass, are often recommended. They provide a gentler touch that can shape and smooth the nail without causing harm to the nail bed or surrounding skin. Understanding the importance of using appropriate tools ensures that nail technicians promote nail health and provide a safe experience for their clients.
