What is a common effect of over-buffing nails?

Over-buffing nails can result in significant nail damage or thinning because the layer of the nail is being excessively removed during the buffing process. Nails are composed of layers of keratin, and when buffed too aggressively or too often, it can lead to a weakening of the nail structure. This can make the nails more prone to breakage, splitting, and other forms of injury. A healthy nail should maintain its natural thickness and integrity, which can be compromised with over-buffing.

Other options, while they can relate to nail care, do not directly align with the primary consequence of over-buffing. For instance, while nail discoloration or adhesion issues may arise from various factors, they are not direct outcomes of the over-buffing process itself. Similarly, increased nail growth is unrelated to the act of buffing, as nail growth occurs at the nail matrix and is unaffected by surface treatments. Thus, the most definitive and immediate effect of over-buffing is the resulting damage or thinning of the nails.
