What can overexposure to certain chemicals do to the nails?

Overexposure to certain chemicals can lead to weakening and damaging the nails due to their harsh properties. Many chemicals found in nail products, such as acetone, formaldehyde, and various solvents, can strip the nails of their natural oils and moisture. This results in brittleness, splitting, and peeling of the nails. Additionally, prolonged exposure to these substances can irritate the surrounding skin and may lead to allergic reactions, compounding the damage.

In contrast, the other choices suggest positive benefits or no impact on nails, which do not align with the realities of chemical exposure. Nail growth enhancement and strengthening are typically achieved through proper care and nutrition rather than through exposure to damaging chemicals, while the claim that there is no effect ignores the well-documented risks associated with harmful substances commonly used in nail care.
