What can excessive exposure to water do to the nails?

Excessive exposure to water can lead to nails becoming weak and brittle, which often results in chips and splits. When nails are submerged in water for long periods, they absorb moisture, causing them to swell. Once they dry, they may contract and lose some of their strength, making them more prone to breaking or chipping. This cycle of swelling and contracting can lead to significant damage over time, highlighting the importance of keeping nails moisturized without overexposing them to water.

Strengthening, promoting healthy growth, and adding shine are all benefits that can be achieved through proper care and use of appropriate nail products, but too much moisture from prolonged water exposure does not contribute to these outcomes.
