Repeated gel manicures, daily wear, and even simple tasks like typing can leave nails prone to splitting, peeling, or breaking. Nail strengtheners, experts say, are a simple yet effective way to repair damage and support natural growth, giving nails the protection and nourishment they need.
Why Nails Become Weak
Over one in four women experience onychoschizia, or nail fragility, according to Harvard Medical School. Factors such as dehydration, nail-biting, harsh chemicals, and everyday mechanical stress can cause nails to become brittle. Nail strengtheners provide essential nutrients like calcium, magnesium, and vitamins A, C, and E, which help rebuild and fortify nails over time.
