What is a nail that has a dramatically increased curvature called?

A nail that has a dramatically increased curvature is referred to as pincer nails. This condition is characterized by an abnormal curling of the nail, where the sides of the nail grow inward, often causing discomfort and potential pain for the individual. Pincer nails can occur due to various reasons, including genetic factors or underlying health conditions.

In differentiating this from other types of nails, flat nails typically present as having little to no curvature, while curling nails do not necessarily indicate the same severity of inward growth as pincer nails. Club nails, on the other hand, involve a broader and more rounded nail plate and can be associated with certain medical conditions but do not specifically describe the increased curvature found in pincer nails. Understanding the specific characteristics of pincer nails is essential for proper identification and potential treatment in a salon or clinical setting.
