Nail erosion is primarily caused by frequent exposure to water and harsh chemicals. This exposure can weaken the nail structure, leading to thinning and erosion. When nails are consistently exposed to water, they can become softened and more prone to damage. Harsh chemicals, such as those found in cleaning products or certain nail products, can also strip the nails of their natural oils and moisture, making them more susceptible to erosion and breakage. This is particularly important for nail technicians to understand, as they often use various products and have hands in water frequently during their work, which can impact nail health.

The application of nail polish, while it may have some effects when removed improperly, does not typically cause erosion by itself. Similarly, the excessive use of moisturizers would generally benefit the nails and cuticles rather than lead to erosion. Natural nail growth is a normal biological process that does not contribute to erosion but can sometimes reveal issues with the nail bed or health as the new growth emerges.
